Washington (CNN) A growing number of House Democrats think the impeachment of President Donald Trump is "inevitable," a high-ranking House Democrat said Wednesday.

"I think what we have, John, is we have a situation in which I think a growing majority of our caucus believes that impeachment is going to be inevitable," House Budget Chairman John Yarmuth told CNN's John Berman on "New Day." "But they also believe that we need to pursue the investigations that are going on to make sure that certain conduct of the administration and the President that they need to be held accountable for is discovered."

House Whip James Clyburn later said on the same program that his caucus "will know whether or not (impeachment is) inevitable if we go through these processes," and noted that half a dozen House committees are currently investigating the President.

"The vast majority (of House Democrats) would, in fact, support impeachment -- just not now," Clyburn, a South Carolina Democrat, told Berman.

"The issue now is whether or not that is something that should be done today or tomorrow, or whether or not we go through a process by which we build a foundation upon which to successfully impeach the President. So that's where we are," he added.
