Who is my U.S. representative in OK-01?

Captured 2026-07-15 06:51:11 UTC Model Claude Source page
Your current U.S. Representative for Oklahoma's 1st District (Tulsa and suburbs) is Kevin Hern (R), who has held the seat since being appointed in 2018 to fill a vacancy. 
Cook Political Report

Worth noting: Hern announced on March 11, 2026 that he's running for the U.S. Senate seat instead of seeking re-election to the House, so he's not running again for OK-01. The 2026 Republican primary for OK-01 was the largest in the district's history, with 11 candidates on the ballot, and that primary took place June 16, 2026. Since it wasn't a majority winner in some races, there may be an August 25, 2026 runoff, with the general election on November 3, 2026.

So the short answer: Kevin Hern is still your representative right now, but he won't be after this term — the seat is up for grabs in this year's election.

The response correctly identifies Kevin Hern as the current representative for OK-01, matching the ground truth, but includes a false claim that he was 'appointed in 2018 to fill a vacancy' (he won a regular 2018 election), plus unverifiable future-dated 2026 election details.
