Donald Trump spent his last moments as President sad and alone, according to Jim Acosta, who led CNN's coverage of Trump during his presidency. In his farewell to Washington on Wednesday morning, Trump greeted a small crowd of about 200 at Joint Base Andrews before he boarded Air Force One with family and the press, including Acosta. "It was sort of a sad and pathetic sight," Acosta told CNN's Chief Media Correspondent Brian Stelter on "Reliable Sources" on Sunday. "I've never seen him this alone the entire time he was at the level of presidential politics."
