Defense Secretary Pete Hegseth joined Republican congressional candidate Ed Gallrein in Kentucky to campaign against Representative Thomas Massie in a high-profile primary that has become a test of President Donald Trump's influence over the party. Gallrein, a former Navy SEAL backed by Trump, is challenging Massie in the state's 4th Congressional District, with the race drawing national attention and record-breaking spending.

Hegseth criticized Massie for opposing key parts of Trump's agenda, arguing that the president needs loyal allies in Congress rather than dissenting voices. Although Hegseth said he appeared in a personal capacity, his presence marked a rare move for a sitting defense secretary. Trump has repeatedly attacked Massie in recent days, urging voters to defeat him and praising Gallrein as a strong supporter of his agenda.

Massie, known for his libertarian positions and skepticism of foreign aid, defended his record and said outside attacks show he is leading in the polls. He pointed to grassroots fundraising support and argued that his independence reflects his commitment to America First principles. The contest has become the most expensive primary for the House of Representatives in history, with more than 32 million dollars spent, much of it by Trump allies and pro-Israel groups.
