Democratic presidential hopeful Bernie Sanders has a plan to create national health insurance, a program he says would be paid for through increased taxes on the wealthy. Just one problem: Two studies today jointly published by left-leaning think tanks argue that, over the course of a decade, there's an $18 trillion gap between the money that taxes would rake in and the cost of his health care plan.

The work from the Tax Policy Center and the Urban Institute suggests that Sanders has just $15 trillion planned in new taxes, while his health care plan would cost the government $33 trillion, leaving the poor and middle class to potentially foot more of the bill than the Vermont senator has budgeted for.

Sanders' policy director, Warren Gunnels, disputed the think tanks' findings.

"This study significantly underestimates the savings in administration, paperwork, and prescription drug prices that every major country on earth has successfully achieved by adopting a universal health care program," he said. Julie Kliegman

The Camp Fire has left 71 dead and more than 1,000 missing throughout northern California. It's also spread some of the dirtiest air in the world to San Francisco and beyond.

After burning for more than a week, 50 percent of the blaze had been contained as of Friday night, the California Department of Forestry and Fire Protection said. Reports of missing people swelled from more than 600 on Friday to 1011, Butte County Sheriff Kory Honea tells CBS News. Honea also warned the list was "dynamic" and could grow or shrink as those who don't realize they've been reported missing come forward.

Meanwhile, air quality in northern California has reached levels as poor as cities in China and India. It’s nearly impossible to navigate the "apocalyptic fog" surrounding the fire, The New York Times writes, and hospital workers say reports of respiratory complications have surged. Nearly 200 miles south in San Francisco, the city’s iconic trolleys have been pulled from the streets amid smoky air. Residents have taken to wearing respiratory masks, schools have closed, and the so-called "Big Game" between the University of California, Berkeley and Stanford University has been postponed.

The CIA has "high confidence" that Saudi Crown Prince Mohammed bin Salman ordered the murder of U.S.-based Saudi journalist Jamal Khashoggi, officials first told The Washington Post.

The CIA reportedly drew its evidence from, among other things, a phone call between Khashoggi and bin Salman's brother Khalid bin Salman, in which Khalid told Khashoggi to visit the Saudi consulate where he was killed. The crown prince told Khalid to make the call, per the Post. A team of 15 Saudi operatives then reportedly flew via government airplane to Istanbul for the murder.

The U.S. Treasury Department sanctioned 17 Saudis it said were "involved in" Khashoggi's murder earlier this week. But this is furthest the U.S. has gone toward implicating Saudi Arabia for the crime, per reports from multiple sources.

Khashoggi was killed after entering the Saudi consulate in Istanbul on Oct. 2, and Turkey has long maintained the Saudi government was responsible. Saudi Arabia once said the murder was a predetermined rogue operation, but shifted to say it was a random killing when announcing charges against 11 alleged perpetrators earlier this week. Bin Salman is close with President Trump's son-in-law and senior adviser Jared Kushner, and some have suggested the Trump administration avoided implicating Saudi Arabia to preserve an alliance with the country.

A spokeswoman for America's Saudi consulate told the Post that the CIA's claims in its "purported assessment are false." Kathryn Krawczyk

Democrat Stacey Abrams on Friday said that it was not possible for her to win the gubernatorial race in Georgia, admitting defeat against Republican Brian Kemp, who had already declared victory in the hotly contested race, reports NPR.

On Election Day, the race was too close to call, and Abrams accused Kemp of suppressing votes as Georgia's secretary of state in an effort to become governor. "I acknowledge that [Kemp] will be certified the victor in the 2018 gubernatorial elections," Abrams said, saying her remarks were not a concession speech. "Concession means to acknowledge an act is right, true, or proper. ... I cannot concede that." She said she would file a federal lawsuit to contest the "gross mismanagement" of the election. Abrams' campaign has said there was evidence of "misconduct, fraud, or irregularities" that may have been enough "to change or place in doubt the results."

Kemp responded to her speech by applauding her "passion and hard work," but said "we can no longer dwell on the divisive politics of the past" and must "move forward." Watch Abrams' remarks below, via CBS News. Summer Meza

President Trump once convinced drug manufacturer Pfizer to curb its price hikes. This time, he may not be so lucky.

America's biggest drug manufacturer announced Friday it would increase prices on 10 percent of its prescriptions in January, Bloomberg reports. The move comes after Republicans lost the House in last week's midterms — something experts suggest isn't a coincidence.

The price hike affects 41 prescription drugs in Pfizer's portfolio, The Wall Street Journal has learned. Most of the drugs will see a 5 percent price increase, but some could be up to 9 percent. "Newly approved medicines and sterile injectables" aren't included in the hike, the Journal writes.

Pfizer announced a similar increase on more than 40 drugs back in July, with many slated for price hikes of 9.4 percent and even higher. Trump quickly criticized the move on Twitter, and after a conversation between the president and Pfizer CEO Ian Read, Pfizer said it would delay the increases "to give the president an opportunity to work on his blueprint to strengthen the health-care system."

After Friday's revelation, Andy Slavitt, the former head of Medicare and Medicaid, suggested in a tweet that Pfizer was "back to business" now that the midterms are over. After all, Democrats will soon take over the House, limiting Trump's ability to revamp the health-care system. Trump also still hasn't enacted his plan to lower drug costs, Bloomberg notes. And Read, who the Journal says "supports the Trump administration," is stepping down as Pfizer's CEO in January.

A spokeswoman for Health and Human Services Secretary Alex Azar criticized the move, telling Bloomberg it shows the "perverse incentives of America's drug pricing system." Kathryn Krawczyk

First they're sour, then they're sweet. Now, they're a cereal.

That's right, Sour Patch Kids, the gummy candy shaped like small children, is joining the likes of Reese's and bringing candy to the breakfast table. Sour Patch Kids cereal will make its debut Dec. 26, and will be sold exclusively at Walmart, reports Today.

Unlike other candy cereals like Post's Oreo O's, which create delicious chocolate milk in your bowl, the $3.98 neon-colored box of Sour Patch Kids cereal will purposefully turn your milk sour. The cereal will have a "sour coating" and "sweet finish," just like the candy, says Mashable.

If you actually want to try this questionable concoction, Today says you'll find it on various retailers' shelves across the country starting in June 2019. Don't worry, you don't need ID to buy it. Taylor Watson

President Trump got a boatload of flack for not making the traditional Veterans Day visit to Arlington National Cemetery. And unlike his rainy day debacle in France, he doesn't have anyone else to blame.

In a Friday interview, Fox News' Chris Wallace asked Trump why he didn't stop by Arlington earlier this week. "I should have done that," Trump responded, before adding that he "was extremely busy on calls for the country." Still, in what The Washington Post's Josh Dawsey called "a rare showing of regret," Trump continued to say "in retrospect he should have" made the visit and he "will virtually every year."

On Saturday, Trump also skipped a rainy World War I memorial service just outside Paris due to what the White House called "scheduling and logistical difficulties caused by the weather." But the president wasn't bogged down by international calls that time — It was apparently the Secret Service's fault. Kathryn Krawczyk
