A Republican Senator who voted to convict President-elect Donald J. Trump after the sham January 6 impeachment trial is now facing a serious primary challenge. Louisiana Senator Bill Cassidy will face a primary challenge from state Treasurer John Fleming in the 2026 election.
Fleming, who held various roles during the first Trump administration and previously served in the House of Representatives, announced his candidacy on Wednesday. The Louisiana Treasurer criticized Cassidy for lacking support for Trump and “America First” principles.
“Senator Cassidy has failed the people of Louisiana,” Fleming stated in his announcement. Cassidy, now the incoming chairman of the Senate Health, Education, Labor, and Pensions Committee, has not yet formalized his reelection plans. However, in a recent interview, he expressed his commitment to preparing for the 2026 race.
According to data from the Federal Election Commission (FEC), Cassidy has accumulated over $5.8 million. Despite the modest war chest, the Louisiana Senator is viewed by many as being especially vulnerable to a primary from a strong MAGA candidate.
Trump, who has previously questioned Cassidy’s loyalty, criticized the senator on Truth Social earlier this year. “One of the worst Senators in the United States Senate is, without question, Bill Cassidy, A TOTAL FLAKE, Republican though he may be,” Trump wrote, recalling: “When the Democrats’ Impeachment Hoax started, this Lamebrain Senator actually voted against me.”
Senator Cassidy also serves on the Senate Finance Committee, which is set to scrutinize Robert F. Kennedy Jr., whom President-Elect Trump has nominated to head the Department of Health and Human Services (HHS). Along with several others, Senator Cassidy has received large amounts of campaign cash from Big Pharma, which RFK Jr. has challenged.
