Updated 8:56 p.m. | President Donald Trump wasted little time at a Montana rally Thursday painting Democratic Sen. Jon Tester as a “liberal” who tells Big Sky Country residents one thing and then votes the opposite way.

“I see Jon Tester saying nice things about me, but I say, ‘But he never votes for me,’” the president said of Tester’s votes against most of the Republicans’ top agenda items. “Tester doesn’t share your values. … Jon Tester says one thing when he’s in Montana. But I’m telling you … he does the exact opposite.”

Trump made clear at the event in Great Falls that he still holds a grudge against Tester over the failed nomination of Ronny Jackson, a Navy rear admiral and the president’s former military physician, to become Veterans Affairs secretary. Tester brought to public light allegations from whistleblowers about questionable management and conduct against Jackson that led to his decision to step aside.

“Tester showed his true colors with his … attacks on a great man, a friend of mine. … I sort of feel guilty about this whole thing,” Trump said. “Jon Tester said things about him that were horrible and not true. That’s probably why I’m here. I won Montana [in 2016] by so many points, I don’t have to come here.”

(Senate Veterans Affairs Chairman Johnny Isakson, R-Ga., has backed Tester’s actions; the Defense Department inspector general has launched an investigation into Jackson’s behavior.)
