Just about every day since he became president, Donald Trump has started his morning by taking to Twitter.
Trump's messages to his nearly 33 million followers are frequently hostile and confusing, but the president may have topped himself today.
In a shocking and seemingly unprovoked attack on Morning Joe host Mika Brzezinski, Trump raised eyebrows - even more than usual.
With no context provided, Trump launched a tirade against Brzezinski and her co-host, Joe Scarborough, claiming that the MSNBC personalities unfairly criticize him on air as a result of personal grievances:
"I heard poorly rated @Morning_Joe speaks badly of me (don't watch anymore)," Trump tweeted.
"Then how come low I.Q. Crazy Mika, along with Psycho Joe, came.....to Mar-a-Lago 3 nights in a row around New Year's Eve, and insisted on joining me."
"She was bleeding badly from a face-lift. I said no!"
What Brzezinski's possible plastic surgery procedure has to do with Morning Joe's coverage of the Trump administration is anyone's guess.
In any case, the baffling nature of the tweet hasn't stopped Trump advocates like Sarah Huckabee Sanders from defending the president's actions.
Sources who have spoken to Sanders report that she's arguing the tweet was part of Trump's effort "to push back" and "fight fire with fire."
The president "won't be bullied by liberal media," after all.
For her part, Brzezinski responded to the firestorm with a reference to Trump's most famous anatomical shortcoming:
The 50-year-old political commentator posted the above photo sans caption - and obviously, this is a case in which no explanation is necessary.
But while Brzezinski effectively clapped back at the president without using words, many others have come to her defense with scathing condemnations of Trump's appalling tweet.
Reads a statement issued by MSNBC:
"It's a sad day for America when the president spends his time bullying, lying and spewing petty personal attacks instead of doing his job."
Tweeted Senator Lindsey Graham.
"Mr. President, your tweet was beneath the office and represents what is wrong with American politics, not the greatness of America."
Speaking through her press secretary, Melania Trump defended her husband with an argument similar to Sanders', however.
According to the office of the FLOTUS, our 45th Commandier in Chief is under constant attack and is merely responding in kind.
Stephanie Grisham stated on the First Lady's behalf:
"As the First Lady has stated publicly in the past, when her husband gets attacked, he will punch back 10 times harder."
This is far from the first time that Trump's Twitter account has been a source of controversy. (Not in the past week, even.)
Still, such a brazen personal attack on a media personality from a sitting president is thoroughly unprecedented.
Trump has yet to personally respond to the uproar over his latest insult ... but give it a couple of hours. Most likely via Twitter.
