Republican Rep. Cory Mills lost his Florida congressional primary on August 18, 2026, to challenger Ryan Elijah, ending Mills's bid for another term in the U.S. House of Representatives. The defeat came as Mills faced an ongoing House Ethics Committee investigation, which had dogged his campaign in the final stretch of the race.

Elijah, who ran as the alternative to the incumbent, secured the Republican nomination in what observers across the political spectrum characterized as a significant upset. The Florida district will remain safely Republican in the general election, but the primary outcome reflects the political damage that ethics-related scrutiny can inflict on an incumbent even within their own party.

Mills had previously been associated with support from former President Donald Trump, but the Ethics probe reportedly undermined his standing with Republican primary voters. The investigation's details, combined with broader campaign scrutiny, proved difficult for Mills to overcome despite his incumbency advantage.

The race drew national attention as an early indicator of how ethics controversies may shape competitive primaries in the lead-up to the November 2026 midterm elections. Elijah will now face the Democratic nominee in the general election in a district that Republicans are expected to hold.
