President Donald Trump has been in office for less than a month, but Rep. Maxine Waters, D-Calif., already has her eye on removing him. Waters and House Minority Leader Nancy Pelosi, D-Calif., held a news conference Monday to outline their disagreements with the Republican and debate the possibility of impeaching him, Politico reported.

Though Pelosi said Trump hasn't broken the law in a big enough way to necessitate impeachment yet, Waters said he was "leading himself" into legal trouble.

"I think that he's leading himself in that kind of position, where folks are going to ask, 'What are we going to do?' and the answer is going to be, 'Eventually, we've got to do something about him,'" CNN reported Waters said. "We cannot continue to have a president who's acting in this manner. It's dangerous to the United States of America."

Waters, a 27-year congresswoman who on Jan. 31 introduced a bill calling for an investigation into Trump's connections with Russia, elaborated in a video posted to her Twitter Monday. She acknowledged that Republicans hold the majority of votes in both the House of Representatives and Senate but remained optimistic about lawmakers' grounds for resisting Trump.

"When I've talked about leading him to impeachment, what I'm really saying is he has done enough in the short period of time for questions to be raised about whether or not he's acting in the best interest of this country," Waters said in the video.

Waters specifically mentioned Trump's alleged relationship with Russian President Vladimir Putin, whose leadership been accused of interfering in the election and hacking top Democrats to take down Hillary Clinton. The connections between Trump and Putin have drawn attention as recently as Sunday, when Trump did not condemn the Russian leader during an interview with Bill O'Reilly, the Washington Post reported.

In the interview, Trump said that he respected Putin. When O'Reilly declared Putin a killer, Trump responded, "There are a lot of killers. We have a lot of killers. Well, you think our country is so innocent?"

Presidents can only be impeached for treason, bribery or other high crimes and misdemeanors, according to the Constitution. Only two have been impeached: Andrew Johnson, in 1868, and Bill Clinton, in 1998. Neither were forced out of office.
