Democratic front-runner Hillary Clinton will testify on Thursday in front of a Republican-led committee about the 2012 attack in Benghazi, Libya, that killed four Americans.

What she says could have major implications for her campaign for the presidency.

Here’s what you need to know about the attack and the investigation, according to NBC News and the Associated Press.

Attackers scaled the wall of a U.S. diplomatic outpost in Benghazi on Sept. 11, 2012. The compound was not reinforced and a group of attackers were able to open a gate and set fire to the building.

The attackers were a disorganized group of militants who decided at the spur of the moment to storm the compound, according to then-acting CIA Director Michael Morell.

Police in New Jersey have issued an arrest warrant for a white supremacist who made headlines for naming his children after Adolf Hitler and other members of the Nazi Party.

Holland Township Police in Hunterdon County put out a social media plea for the arrest of Isidore "Heath" Campbell, 42, after an alleged assault. Police have not released details of the incident but said Campbell will be charged with aggravated assault.

Campbell and then-wife Deborah Campbell gained national attention in December 2008 after a ShopRite supermarket in Greenwich Township, New Jersey, refused to write the name of their son – Adolf Hitler Campbell – on a cake for his third birthday. The couple complained the refusal constituted discrimination. A Pennsylvania Walmart store later made the "Hitler" birthday cake.

In 2013, Campbell – dressed in Nazi uniform – marched into a New Jersey courthouse to petition a family court judge to allow him to see his youngest son. The New Jersey Division of Youth and Family Services said they took the boy because of previous violence in the home.

"I'm going to tell the judge, 'I love my children. I want to be a father; let me be it,'" Campbell told NBC10 before court proceedings. "Let me prove to the world that I am a good father."

The father of four, who gave his children the Nazi-inspired names Adolf Hitler Campbell, JoyceLynn Aryan Nation Campbell, Honzlynn Jeannie Campbell and Heinrich Hons Campbell, lost custody of his children but was given visitation rights.

Police asked anyone who knows about Campbell's whereabouts to call 908-995-4670.

Investigators in the Lehigh Valley called the death of a 26-year-old woman inside her home Wednesday morning suspicious.

A deputy coroner declared Jillian Rohrbaugh dead around 11:50 a.m. in her home along S 5th Avenue near Center Street in Whitehall, Pennsylvania, said the Lehigh Valley Coroner’s Office.

The coroner’s office didn’t reveal any details about the death outside of saying that the Lehigh County District Attorney’s Office’s Homicide Task Force would investigate and that an autopsy would be performed Thursday.

Police are investigating after a stray bullet struck a home in a Philadelphia neighborhood early Thursday morning.

The incident happened about 1 a.m. in the 7500 block of Brockton Road in the Overbrook Farms neighborhood.

The female homeowner told police she was sleeping when she was awakened by breaking glass.

She walked to the back bedroom and noticed glass on the floor and a bullet casing on the ground.

No one was injured.

Investigators are working to determine where the bullet came from.

A driver lost control and slammed into several parked cars in a Philadelphia neighborhood early Thursday morning.

The incident happened about 1 a.m. near the intersection of 4th and Cambria Streets in North Philadelphia.

According to investigators, the driver somehow lost control of his car and crashed into several parked cars.

The car then flipped over before it came to a stop after hitting the front of a house.

A total of four cars were damaged. The home sustained minor damage. The striking car was totaled.

The driver was treated for minor injuries.

It was not immediately known if any charges would be filed.

Thanksgiving has traditionally been known as a holiday to spend time with your loved ones. But a recent trend has seen people scarfing some turkey early and then heading to the mall to score some shopping deals.

However, the staff at the Deptford Mall in South Jersey wants to buck that movement.

The Deptford Mall is scheduled to open at 6 p.m. Thanksgiving night and stay open until midnight.

A letter posted on Change.org titled "Do Not Open Deptford Mall On Thanksgiving Day" is intended for Jim Mackey, the mall’s senior property manager.

A portion of the letter reads "it is taking people away from a holiday that is based around spending time with friends & family."

The letter states that this is the "first year Deptford Mall has decided to open at such an early time."

NBC10 reached out to representatives with the Deptford Mall, but did not immediately hear back.

As former Secretary of State Hillary Rodham Clinton prepares to testify about the deadly 2012 attacks that killed four Americans in Benghazi, Libya, the frustrated mother of a man who died in the violence is demanding "the truth for a change."

San Diego resident Patricia Smith lost her son, Sean, in the Sept. 11, 2012 attack, when insurgents stormed the U.S. Embassy in Benghazi and overwhelmed security. They killed four Americans: Sean Smith; U.S. Ambassador Chris Stevens; and former Navy SEALs Tyrone Woods, of Imperial Beach; and Glen Doherty, of Encinitas, California.

Sean was a state department communications specialist, and his mother said more than three years after his death, she is still waiting for answers from Clinton.

"Why does she get to know what happened and I don't? What is so… it was her department. How come she let my son be killed, how come? She knew this was happening," said Patricia Smith.

Patricia Smith said the state department told her she was not a member of Sean’s immediate family, so did not have to release details of his death to her.

She hopes to get some answers when Clinton goes before the House Select Committee on Benghazi on Capitol Hill Thursday. Clinton, a Democratic candidate for president, was the U.S. secretary of state during the attacks.

"I hope she opens up her mouth and says something that's the truth for a change," Patricia Smith said. "She promised she would get back to me and tell me what happened; she has never, ever communicated with me."

Committee chairman Trey Gowdy said he wants to ask Clinton why U.S. security was not enforced as the conditions in Libya got worse. But in recent weeks, some Republicans have suggested Clinton herself is the panel's target.

During last week's Democratic debate in Las Vegas, Clinton said she'll answer all questions but believes this is a concerted Republican effort to derail her campaign.

"This committee is basically an arm of the Republican National Committee," she said. "It is a partisan vehicle as admitted by the House Republican Majority Leader Mr. McCarthy to drive down my poll numbers."

One committee member, U.S. Rep. Adam Schiff, a Democrat from California, agreed with Clinton’s view.

"After 17 months, $4.5 million, we have nothing new to tell the families, apart from that there was a private email server," said Schiff. "That doesn't tell us anything about Benghazi."

Five House committees and two Senate committees have held hearings on Benghazi. Clinton testified at two of them, taking responsibility for the tragedy and agreeing to improve security at diplomatic outposts.

Thursday marks the first time Clinton will testify before Congress about the private server she used for emails during her time as secretary of state.

A bicyclist was taken to the hospital after they were struck by a car that left the scene in Delaware County Thursday morning.

The incident happened about 6 a.m. along Route 202 in Glen Mills.

According to investigators, a person riding a bike was struck by a car. The individual was taken to Crozer- Chester Medical Center in an unknown condition.

Investigators say the driver left the scene and remains on the loose.

So far, no arrests have been made.

A suspected arsonist targeted a seventh St. Louis-area church Thursday morning, authorities said, NBC News reported. 

Firefighters responded to the Shrine of St. Joseph just after 1:30 a.m. The front doors of the rectory had been burned with a small amount of accelerant, the St. Louis Fire Department said in a news release. The rectory was empty at the time and there were no reported injuries.

St. Louis Police Chief Sam Dotson said the fire appears similar to the other recent arsons in the St. Louis area in which only the front doors of churches were burned.

While the Shrine of St. Joseph has a mostly white congregation, many of the other churches are predominantly black, according to NBC affiliate KSDK. No known motive has been suggested by authorities. 

A young American commando was killed when U.S. special operations forces conducted an operation to free dozens of hostages who faced imminent execution by ISIS in Iraq, U.S. officials said Thursday.

The commando was the first service member to die in combat operations against the militant group.

U.S. special operations forces rescued 70 hostages after receiving intelligence that there was about to be a mass execution, U.S. officials told NBC News.

There were varied reports on who the rescued hostages were: Kurdish fighters, Iraqi fighters, or a mix of those and other groups.

It is the first publicly-acknowledged mission of U.S. special operations forces conducted in Iraq since President Barack Obama sought authorization from Congress in February for "limited" ground combat operations against ISIS.

For the most part, "selfies" are harmless and often a creative way to snap a photograph. But for one New Jersey couple, their "selfies" led to their arrest.

The bizarre chain of events began on October 13 when a woman’s iPad was stolen from her car that was parked outside a Starbucks on Route 73 in Evesham Township, New Jersey.

Police say the suspects -- 38-year-old Lawrence Segers III and 26-year-old Katovia Williams -- took "selfies" with the victim’s iPad.

During the investigation, the victim reported that pictures of an unknown male and female surfaced through her iCloud account.

Investigators were able to identify the couple with the assistance of the Lindenwold Police Department.

Segers III and Williams were arrested Wednesday.

The suspects, both of Voorhees, have been charged with 3rd degree Burglary and 4th degree Theft. They are being held at the Burlington County Jail.

The stolen iPad was recovered and will be returned to the victim.

Russian President Vladimir Putin is quite popular in his home country. 

The Russian leader enjoys a nearly 90 percent approval rating according to a nationwide poll published Thursday, NBC News reports. 

Pollsters in Russia credit his high ratings to military moves in Syria.

"Such high approval rating of the president of Russia had to do mostly with the events in Syria, [and] Russian airstrikes on terrorist positions," VTsIOM said on its website.

The poll surveyed 1,600 people and had a margin of error of 3.5 percentage points. 

Donald Trump's comments suggesting he would be open to shutting down U.S. mosques if a worshiper is linked to ISIS are being condemned as "un-American" and "un-presidential."

When asked by Fox Business Channel's Stuart Varney whether he agreed with British Prime Minister David Cameron's proposal earlier this week to close "extremist" mosques, Trump said, "I would do that, absolutely."

Varney questioned the legality of Trump's response: "Can you close a mosque? We do have religious freedom."

"It depends," Trump said, "if the mosque is, you know, loaded for bear."

In a statement Wednesday, the Council of American-Islamic Relations (CAIR) asked the GOP frontrunner to better explain his definition of "extremism" and to elaborate on the criteria his administration would use to close any house of worship.

"Donald Trump's apparent willingness to close down American mosques that he deems 'extreme' is totally incompatible with the Constitution and our nation's cherished principle of religious freedom," CAIR's government affairs department manager Robert McCaw said in the statement.

The statement went on to point out: "Even Rep. Peter King of New York, who has often been criticized for his Islamophobic views, condemned Trump's remarks."

Last month, Trump was criticized by Muslim groups for his failure to challenge a supporter who said, "We have a problem in this country. It's called Muslims."

The presidential contender has drawn the ire of various groups since officially launching his campaign in June. During his presidential run kick-off speech, Trump said Mexican immigrants are "rapists," among other things. He refused to apologize.

In August, Trump said in an interview with NBC's Chuck Todd, that if elected, he would reverse President Barack Obama's executive orders on immigration and deport all undocumented immigrants.

ALREADY SAW LOTS OF FORECASTS?

If you follow weather, even a little bit, you’ve surely heard someone’s forecast for the coming winter. Chances are, you’ve heard several. Some come from “official” sources (Climate Prediction Center), some from respected meteorological firms (The Weather Channel), and some that I’ll just call “other”. People start asking about the winter forecast even before the previous winter is over. There’s more and more pressure to issue one earlier each year.

WANT A FORECAST FOR OCTOBER 25, 2060?
If there’s enough demand for it (especially if someone is willing to pay for it), there will be someplace that will give them a forecast for a specific date 45 years from now. Why not? No one will ever find out if it’s right or not. And a specific day’s forecast 45 years from now will be every bit as accurate as one 45 days from now. That’s because both have ZERO SKILL! That is, neither will be better than flipping a coin. I use 45 days/years because AccuWeather has been using specific 45 day forecasts for a while. And I’m sure there are people who take it seriously, because they want to know. There are even companies that already do specific forecasts for an entire year. And they make money doing it!

AT BEST, SEASONAL FORECASTING IS DIFFICULT
While there is no evidence that anyone can predict weather for specific days beyond a couple of weeks, more generalized forecasts of the next few months has shown some skill. It’s more like a little skill. It is better than flipping a coin, but not by a lot.

I started doing winter forecasts of some sort in 1997, which just so happened to be when the strongest El Nino in history was developing. That was no accident. There had been some recent scientific papers that connected strong El Niño’s with warm, nearly snow-free winters in our part of the world. And I went on the air and predicted that. We ended up with less than one inch of snow for the entire winter!

The problem was that now people thought we could predict for the winter season all the time! And when people (in my case, known as TV viewers) demand something, we tend to give it to them. It’s like the business slogan, “The customer is always right.” My bosses had that philosophy, so now we had to make a winter forecast every year, sometime in November. They promoted them heavily, and the ratings actually spiked on those nights. So what happened? Every other station started doing it, too. After all, the people had spoken!

This was all wonderful, except for the fact that no future winter was as clear-cut as the first one. We had some successes and failures in the 17 years since then. The science of seasonal forecasting has improved a bit, but there are still important factors that simply don’t show up until November. That is why, no matter who asks, I tell them that it’s “too soon”. But the research has been going on since summer ended, and there are some big things to look at this year.

FACTORS FOR 2015-16 WINTER:
EL NINO
Of course, El Nino is what everyone is talking about. It may be just as strong, or even stronger, than the one in ’97-’98. But no two weather patterns are the same, and no two ocean patterns are the same. Take a look at the maps, side by side, of ocean temperatures (compared to “normal”) then and now:

Yes, the area of super-warm water in the Tropical Pacific (middle of the screen) looks the same. But freeze the video at the end and you’ll also see very warm water far north of the El Nino area. The area off of California has been called “The Blob”. There’s another warm area not far off the Alaska coast. Those are major differences from 1997, and we can’t just ignore them. If they weren’t there, I would likely be predicting a warm winter with very little snow. But they are there.

“THE BLOB” & OTHER PACIFIC WARMTH
Those other areas of very warm water in the Pacific are not as mysterious as some are saying. They are part of other natural oscillations known as the PDO and EPO. Those areas had a lot to do with the past two rough winters in the Eastern U.S. That was a big factor in the 100”+ of snow that Boston got (even New York City had more than 50” in each of the past two winters). We’ve been on the edge of the real snowy winter area both years. Those warm blobs are a factor pointing at colder and snowier for us.

SNOW COVER IN EURASIA (AND BEYOND)
This is the main reason I want to wait until November to make a winter forecast. The increase in snow on the ground across the world in Eurasia has a very high correlation with our winter weather. And the most important number is the increase during the month of October. So we have to wait until that data is in. It’s not just a statistical relationship that is coincidental: researchers have shown how the snow cover there actually changes weather patterns across the world that eventually affect us. Snow in Canada is another factor, but, believe it or not, the correlation isn’t as strong as Eurasian snow.

TO SUM IT UP:
Of course, there are other factors across the globe, from soil moisture in the U.S. to winds way up in the stratosphere. That’s part of the problem: there are so many factors that they sometimes cancel each other out.

We were able to get severe winters in the Northeast U.S. in the past two years even without the extreme Arctic and North Atlantic blocking patterns. Those led to the severe winters from 2009-11. What if we somehow combine the extra storminess due to the El Nino, PLUS the Blob influence PLUS Arctic blocking as a result of the Siberian snow? Then we have the potential for a BIG winter. Information coming in the next week or two may be the determining factors.

Stay tuned.

Russia's Ambassador to the United Kingdom, Alexander Yakovenko, gained unexpected attention Wednesday morning after he posted a tweet that was critical of United States' policy in Iraq.

"US threatens to stop helping Iraq against ISIL if Baghdad asks Russia for help. The terrorists must be rejoicing," Yakovenko tweeted, and included a photo that showed a bearded man in a turban laughing.

Actor and former White House official Kal Penn pointed out on Twitter that the image is actually a scene from the 2008 stoner comedy "Harold & Kumar Escape from Guantanamo Bay." Penn played Kumar Patel, an Indian American character, donning a fake beard, wig and turban, and joking about being a terrorist.

Penn thanked the ambassador in a tweet with an image of Ivan Drago, a fictional Russian character played by Swedish actor Dolph Lundgren from the 1985 film, "Rocky IV."

Battling a rare form of cancer was already taking a toll on Issac Harrison and his family.

One month shy of his first birthday, Isaac is now fighting to survive an overdose of chemotherapy his father said was administered by the Philadelphia hospital where Isaac was diagnosed and initially treated.

"It’s like a nightmare," Kwamane Harrison said, adding his son’s cancer is so rare, doctors told him no one else in the city has it.

Since there have only been six known cases in medical history, doctors said they would have to come up with their own formula for treatment, according to Harrison.

One doctor told the family Isaac may only live a week after being diagnosed.

That was in late August.

Isaac began chemotherapy at St. Christopher’s Hospital for Children, where Harrison said his son was given 10 times the dose of chemotherapy he was supposed to get. That went on for five days, according to Harrison.

"They said this was one of the biggest medical mistakes in 35 years," said Harrison, whose son is now fighting under the care of doctors at The Children’s Hospital of Philadelphia. "He goes through all of these pains, losing hair, crying excessively from all the pain he’s going through."

A spokeswoman for St. Christopher’s Hospital said she couldn't respond specifically to the family's concerns, citing privacy laws. "It remains the focus of St. Chrisopher's Hospital for Children to provide high-quality care to every patient we serve," Kelsey Jacobsen said.

A letter provided by the Harrison family, allegedly from hospital officials, states: 

"Isaac was being treated for a very unusual and serious cancer. The calculation done was inaccurate, resulting in Isaac receiving more chemotherapy than he should have. 

"This complication is a cause for great regret."

Documents from the Harrison family include a Final Report detailing how hospital staff discovered Isaac was given 10x the daily dose of chemotherapy intended due to "a typographic error." Doctors at St. Christopher's called CHOP to begin the transfer process for Isaac.

Isaac is the youngest of five children.

"Nobody wants to hear their child has cancer," Harrison said. "Every day that passes, he's blessed."
