Just hours after she was sworn in, the first Palestinian-American woman ever elected to Congress took aim at President Trump, vowing to “impeach the motherf–ker.”

In a fiery ending to her first day on the job, Michigan Democrat Rashida Tlaib delivered the message at a Thursday reception for the Move On campaign.

The 20-second clip circulating online picks up as Tlaib recalls her historic victory to the crowd.

“And when your son looks at you and says, ‘Mama, look, you won. Bullies don’t win,’ and I said, ‘Baby, they don’t’ — because we’re gonna go in and impeach the motherf—-r,” the Detroit native says as cheers erupt in the room.

On Friday, Tlaib refused to apologize.

“I will always speak truth to power. #unapologeticallyMe,” she wrote.

Then, she fired off a post that said: “This is not just about Donald Trump. This is about all of us. In the face of this constitutional crisis, we must rise.” Another tweet linked to a Detroit Free Press opinion piece about impeaching Trump.

Tlaib is among a record number of women and minorities who were sworn in Thursday as the 116th congressional class. The 42-year-old took her oath using a Koran that belonged to Thomas Jefferson and dates back to 1734.

Tlaib and Rep. Ilhan Omar, a Democrat from Minnesota, are the first two Muslim women to serve in Congress.
