A confidential draft Internal Revenue Service memo directly contradicts Treasury Secretary Steven Mnuchin's reason for not turning over to Congress President Trump's tax returns, The Washington Post reports.

House Ways and Means Chairman Richard Neal (D-Mass.) formally requested Trump's tax returns last month; under a 1924 law, he is one of a handful of top lawmakers with the authority to do so. Mnuchin has refused to give Neal the returns, claiming Congress does not have a "legitimate legislative purpose" to request the documents.

The memo, obtained by the Post, states otherwise, asserting that it is "mandatory" the returns are disclosed, as the law "does not allow the Secretary to exercise discretion in disclosing the information provided the statutory conditions are met." The only way the IRS can refuse to comply with a Congressional subpoena "would be the invocation of the doctrine of executive privilege," the memo states, which has not happened.

The IRS told the Post the draft was prepared in the fall by a lawyer in the Office of Chief Counsel, and does not represent the "official position" of the agency. Trump has not released his tax returns on his own, first claiming that he can't do so because he is under audit, and later saying no one could understand his complex filings anyway. Catherine Garcia

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.
