Rep. Maxine Waters (D-Calif.), one of President Trump's most vocal critics, said Thursday she can “guarantee” that he is colluding with the Russians to undermine American democracy.

Waters, who has repeatedly called for Trump's impeachment, made the statements at a Congressional Black Caucus town hall meeting on civil rights in Washington, D.C.

"Here you have a president who I can tell you and guarantee you is in collusion with the Russians to undermine our democracy. Here you have a president that has obstructed justice. And here you have a president that lies every day," Waters said, as reported by The Washington Examiner.

She also encouraged members of Congress to pursue impeachment.

"How many of you in your organizations have said 'Impeach 45? ... Well, they don't have what it takes, they don't have the laws yet. Impeachment is about whatever the Congress says it is,” she said. “There is no law that can dictate impeachment. What the Constitution says is 'high crimes and misdemeanors' and we define that.

Multiple Democrats have called for Trump's impeachment, but the party's leadership in Congress has urged caution, saying the investigations into last year's Russian election meddling don't yet warrant it.

Waters has become famous on the internet for her harsh words against Trump. In August, she called him “the most deplorable person I have ever met” and that there was “something terribly wrong with him.”

She said prior to his inauguration that she believed Trump would eventually be thrown out of office, and added in April that she would “fight every day until he is impeached.” In her eulogy for comedian Dick Gregory at his funeral this past Saturday, Waters said, “I’m gonna say ‘Impeach 45 everyday, Impeach 45 everyday, Impeach 45 everyday.’”

She has also taken to calling White House staff the “Kremlin Klan” and advocated for an aggressive independent investigation into Russian interference in the election and whether Trump conspired with Moscow.
