Buck will leave Congress after serving in the House of Representatives since 2014. He is currently assigned to the House Judiciary Committee and Foreign Affairs Committee.

Buck was one of three House Republicans who opposed the impeachment of Homeland Security Secretary Alejandro Mayorkas.
Instead of seeking re-election to Colorado's 3rd Congressional District, Boebert announced in December that she would be running for the House seat that's being vacated by Buck. Boebert claimed the decision to hold a special election to fill Buck's vacancy on the same day as the GOP primary was an "establishment" attempt to "rig" the election. (Anna Moneymaker/Getty Images)
