Rep. Rashida Tlaib announced plans during a news conference Wednesday to file an impeachment resolution against President Donald Trump.

The Michigan Democrat aims to introduce the resolution in the coming weeks, a staffer told Roll Call. The move will be one of the first official congressional actions concerning impeachment of the president.

“For me, as a member of Congress, it’s so important that I make sure that I check this president … it’s really important that the president of the United States is investigated,” Tlaib told CNN.

The representative took to Twitter on Wednesday to confirm her announcement, saying “Our democracy must be protected.”
