Trump, Manchin trading barbs as impeachment feud boils over

A post-impeachment spat between President Donald Trump and U.S. Sen. Joe Manchin has sunk to name-calling and insults.The moderate Democrat took to cable news Monday to hurl barbs at the president after a weekend of back-and-forth that ignited when Trump criticized Manchin for voting to impeach him from office.“I expect every American, and myself, would like my president and our president to act like a responsible adult, and he's not,” Manchin told CNN.
