In a subsequent tweet, she added: "This is not just about Donald Trump".
Tlaib's comments went viral on social media and have put Democratic leadership on the back foot, as they have said keeping Trump in check was their priority rather than removing him from office before the 2020 election.
Instead of addressing the profanity, Sanders told "Fox & Friends" on Friday that Democrats attacked the president because of how successful he was. "Donald Trump's actions have harmed the 13th Congressional District and she will not stay silent while this happens".
Speaking at an event organized by progressive group MoveOn, Tlaib recounted a conversation she had with her son.
"We shouldn't be impeaching for a political reason, and we shouldn't avoid impeachment for a political reason", she said.
Rashida Tlaib, who was sworn in on Thursday, said "we're gonna impeach the motherf--" during a celebration party with supporters.
Another pro-Republican account claimed Tlaib's comments actually help Republicans, not Democrats.
Hours after she was sworn in to Congress, Michigan Democratic Rep. But Tlaib - one of the two first Muslim women elected to Congress in November - said she's okay with that reaction, according to CNN.
Democrats spent the past year downplaying impeachment, fearing that it would rally Republicans to Trump's side and knowing that the politics of following through will be dicey even in their best-case scenario.
A reporter in Tlaib's office on Thursday noted the world map hanging on her wall with a minor change. On the map, someone placed a post-it note with the word "Palestine" on it, and an arrow pointing toward Israel. Pelosi is 78, while Tlaib is 42.
Linda Sarsour and others welcome Rashida Tlaib to Congress.
"I identify with her because I'm capable of saying something like that off the top of my head at a rally", she said. During a speech on Capitol Hill, Tlaib promised that she would "impeach the motherf****r", referring to the president.
"The Democrats see the Mueller operation as a vehicle for the impeachment of President [Trump], and I guarantee you that the Mueller operation sees itself as a vehicle for the impeachment of President Trump, too", Tom Fitton, president of the government watchdog Judicial Watch wrote on Twitter. And she did so in the most profane way possible.
