Once House Democrats voted to impeach President Donald Trump, Speaker Nancy Pelosi (D-CA) made the media rounds with the same phrase: "Once a president is impeached, he's impeached for life," she would say with a smile.

"We had confidence- we have confidence in our case that it is impeachable, that this president is impeached for life, regardless of any gamesmanship on the part of Mitch McConnell, however, that could still come to bear," Pelosi told ABC News' George Stephanopoulos last month. "We're still confident in the impeachment and we think it's enough testimony to remove him from office."

On Sunday, House Minority Leader Kevin McCarthy reminded Pelosi of one tidbit she seemed to forget: once the Senate votes to acquit President Trump – which is likely to happen on Wednesday – he will be acquitted for life.

McCarthy put Pelosi on notice during an interview on "Sunday Morning Futures" with Maria Bartiromo on Sunday.

"The president's going to be acquitted for life. Nancy Pelosi needs to know that but what you're going to see right now is a real change in the Democratic Party," McCarthy explained. "There are two internal Civil Wars going on right now: There's many Democrats in the House telling them that they're very upset with the speaker and with Adam Schiff."

According to the House Minority Leader, Democrats are upset with how Pelosi handled impeachment by pursing it "too soon" and not being "fair in the process."

"And she changed the message every single week," he said.

McCarthy said Democrats are upset with Schiff because he failed to tell his Democratic colleagues on the Judiciary Committee he had met with the whistleblower. His own lies have caused the internal war, McCarthy explained.
