This is far from the first time she has called for Trump's impeachment.
Al Jazeera's Andy Gallacher reports.
In another tweet, the president claimed that he "won perhaps the greatest election of all time" and that he has "done nothing wrong (no Collusion with Russian Federation, it was the Dems that Colluded)". There is no requirement whatsoever that a president be charged with or be convicted of a crime before Congress can impeach him.
Meanwhile, Pelosi successfully took back the speaker's gavel, making history (yet again) as the only woman who has ever been speaker of the House.
Drew Hammill, a Pelosi spokesman, subsequently tweeted that "Trump brought up impeachment" in his opening comments at the meeting. "Using language like that in front of her son, and whoever else was there, I thought that was a great dishonour", he said. "I assume she's new", Trump told reporters Friday. And when her comments sparked a furor, she declined to apologize and her office released a statement that read, "The Congresswoman absolutely believes he needs to be impeached".
Ms Pelosi has earned a reputation as a skilled manager and tactician, but she must now walk a fine line in expressing disapproval of Ms Tlaib's remarks - which could complicate ongoing negotiations with Republicans over the budget - while acknowledging the power of the sentiments that they reflect.
Sherman and Green pushed to impeach Trump in 2017 and 2018, but the Republican House blocked those resolutions twice, with the help of Democrats who said the effort was premature.
However, impeachment proceedings in the House would be mostly useless, at least right now.
But when Mr Trump was asked about his critic's comments, he said they were "disgraceful", and "highly disrespectful to the United States of America".
Tlaib's comments came after she penned an op-ed for the Detroit Free Press, calling the president a "direct and serious threat" to the US, and urging impeachment proceedings.
"We ought to be focused on getting people back to work, getting this government operational", House Majority Whip James Clyburn, D-S.C., said. And yes, in addition to calling him a motherfucker, she also said Democrats were going to impeach him.
Emanuel Cleaver of Missouri said: "What she said yesterday was wrong".
Sen. Elizabeth Warren (D., Mass.) wasn't interested Friday in talking about a freshman Democrat's vulgar remark about President Donald Trump.
