The New York City mayors club could not be more splintered.

As one former mayor runs for president and the other one unflinchingly supports the current president, the New York City mayor who's actually in power today has decided to go with a third option. Bill de Blasio, once a 2020 Democratic contender himself, plans to endorse Sen. Bernie Sanders (I-Vt.) for the presidency, and will soon join him to campaign in Nevada, Politico and The New York Times report.

De Blasio campaigned on a progressive presidential platform of his own for a few months last year until dropping out with no traction to speak of. But even though he's positioned himself as a far-left leader throughout his mayoral terms, de Blasio waited until Sanders won the first two 2020 contests in Iowa and New Hampshire before going all in. When exactly de Blasio will announce his endorsement is unclear, but he is expected to head to Nevada on Sunday to start campaigning around the country.

A cross-country tour isn't an unsurprising move for de Blasio, who seemed to be over his mayoral duties and New York City as a whole when he started his 2020 run last year. This reported endorsement of course puts de Blasio at odds with fellow former New York City Mayor Michael Bloomberg, who is running a more centrist 2020 campaign than Sanders. The mayor before Bloomberg, President Trump's ally Rudy Giuliani, is of course way, way further to the right. Kathryn Krawczyk

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.
