White House officials are bracing for the fallout of Special Counsel Robert Mueller's report, anxious they could be revealed as the source of damaging information, NBC News reports.

Attorney General William Barr previously released his summary of the report's main conclusions, saying Mueller did not establish that President Trump's campaign conspired with Russia and did not make a determination about whether the president obstructed justice. But the redacted report, which the Department of Justice says will be released on Thursday, may contain information that could be politically damaging, some of which would have come from current and former White House officials who cooperated.

Some of these officials are experiencing "breakdown-level anxiety" ahead of the report's release, a person close to the White House told NBC, while a former White House official added, "they got asked questions and told the truth and now they're worried the wrath will follow."

It's not clear whether these names would be redacted; Barr has said he would redact information to protect the privacy of "peripheral third parties." But even if they were, a former White House official explained that there are instances where it would be easy to identify the source of information that "applies to just one person." Some of these officials have had their lawyers ask the Justice Department to explain whether they'll be identifiable in the report, but they haven't gotten an answer.

One of those officials who cooperated with Mueller is Don McGahn, the former White House counsel, and ABC's Jonathan Karl reports that what McGahn may have said is "what worries [the White House] most." Brendan Morrow

Mort Drucker, the beloved artist known for his work at MAD magazine, has died at 91.

Drucker died Wednesday at his home in New York, his friend John Reiner confirmed to The New York Times. Reiner told CNN's Jake Tapper his death was not thought to be related to COVID-19.

After joining MAD in 1956, Drucker's hilarious caricatures satirizing pop culture soon became iconic, and he illustrated more than half of the magazine's movie parodies from the 1960s through 2008, per the Times. In a 2000 interview with the Times, he noted, "I think I've drawn almost everyone in Hollywood."

Among Drucker's other notable work includes the poster for George Lucas' American Graffiti; according to The Hollywood Reporter, Lucas personally drove to Drucker's home on Long Island to convince him to draw it.

"The World has lost a not just an extraordinary talent but a shining example of kindness, humility and humor," the National Cartoonists Society said in a statement.

MAD fans on Thursday quickly began sharing their favorite cartoons from Drucker's legendary career, including his parodies of Jaws and Star Wars. "Many of his illustrations are as vivid in my mind as the movies and TV shows that inspired them," The New York Times' Dave Itzkoff wrote.

Reiner told CNN's Jake Tapper that Drucker's final words to him were, "I'm the luckiest man — I've had a wonderful life." Brendan Morrow

First lady Melania Trump is officially donning a face mask during the COVID-19 pandemic, although the jury's still out on whether her husband will follow suit.

In a social media post Thursday, the first lady shared a photo of herself wearing what appears to be a surgical mask, touting the Centers for Disease Control and Prevention's recommendation "to wear cloth face coverings."

"Remember, this does NOT replace the importance of social distancing," she wrote. "It is recommended to keep us all safe."

Melania's masking comes one week after President Trump announced he would not be wearing a mask, despite the CDC-issued guidelines urging people to do so. At the time, Trump implied that it would be odd to be "sitting in the Oval Office, behind that beautiful Resolute Desk" while wearing a mask, so it's unclear how he's taking this news.

The photo of the first lady appears to show her wearing a surgical mask rather than the CDC-recommended "cloth face covering," the former of which is recommended only for use by health care professionals and medical first responders amid critical supply shortages.
