Washington (CNN) A high-ranking Democrat broke with House Speaker Nancy Pelosi on Monday, saying he supports impeaching President Donald Trump and believes impeachment proceedings are inevitable.

"To me it's not a question of 'whether,' it's a question of 'when,' and probably right now is not the right time, but I think at some point it's going to be inevitable," Rep. John Yarmuth told CNN's Erin Burnett on "Erin Burnett OutFront."

The comments put the Kentucky Democrat, who's the chairman of the House Budget Committee, at odds with Pelosi, who said she does not currently support impeaching Trump even though she believes he is unfit to be President, according to a Washington Post magazine interview published Monday. The issue has divided congressional Democrats.

"I'm not for impeachment," the California Democrat said, adding, "Impeachment is so divisive to the country that unless there's something so compelling and overwhelming and bipartisan, I don't think we should go down that path, because it divides the country. And he's just not worth it."
