Sen. Jon Tester (D-MT) is under fire from Republicans following a Washington Examiner report revealing the senator praised a poster depicting former President Donald Trump dead in front of the White House.

“It’s sick and twisted that Dems like Jon Tester are always fantasizing about my father being killed,” Donald Trump Jr., the eldest child of the former president, posted on X on Thursday. Tim Sheehy, the Republican Senate nominee in Montana running against Tester in 2024, also called Tester “sick.”
