California Rep. Kevin Kiley, who formally left the Republican Party last week, has been stripped of his House committee assignments, officials said Thursday.

The change was announced on the House floor as the clerk read letters to House Speaker Mike Johnson, R-La., from the chairs of the Education and Workforce, Transportation and Infrastructure, and Judiciary committees. The letters confirmed that Kiley’s seats on these panels were vacated under House rules. Notices came from Reps. Tim Walberg, R-Mich., Sam Graves, R-Mo., and Jim Jordan, R-Ohio, relayed through House Republican leadership.

Kiley said he left the GOP to remain an “independent voice” for his constituents, without party affiliation “on the ballot or as an officeholder,” though he plans to continue caucusing with House Republicans.

Under Rule X of the House, committee assignments are tied to party membership, meaning members who switch parties or become independents automatically lose their committee seats unless reappointed. Kiley acknowledged this consequence ahead of the official removal and said he intends to seek reappointment despite no longer being a registered Republican.

His departure further narrows the Republican majority in the House, leaving the chamber at 217 Republicans, 214 Democrats, and one independent, with several vacancies creating a slim margin for close votes.

The exit also comes after California’s redistricting reshaped Kiley’s district, pushing him toward a newly drawn, Democratic-leaning 6th Congressional District centered around Sacramento. He has filed to run for reelection without a party preference, framing his move as both a response to “hyperpartisanship” and a political calculation.

Before leaving the GOP, Kiley served on the Education and Workforce, Judiciary, and Transportation and Infrastructure committees, positions that allowed him to influence federal policy on labor, education, courts, and infrastructure.
