According to a report by NBC News, President Donald Trump has called on Montana Senator Jon Tester, who already faces a tough re-election race, to resign. Last week, Trump cryptically claimed to 'know things about the senator' that would cost the incumbent his home-state support. Just days later, Marc Short, the White House's lobbyist on Capitol Hill, told a Montana radio station that the president was making plans to personally campaign against Tester.
