He has a history of independent voting and has occasionally clashed with former President Donald Trump on policy matters, including a short-term government funding bill in March 2025. These disagreements led Trump to publicly endorse Massie's primary challenger, Ed Gallrein, a farmer and former Navy SEAL, urging his removal from office.
