House Republicans spent this week selecting new leaders for several powerful committees, with the chairmen inheriting both a gavel and the task of advancing President-elect Donald Trump‘s agenda through a united GOP Congress.

With the new members’ swearing-in on Jan. 3, 2025, and Trump’s inauguration on Jan. 20, the newly selected House committee leaders will have the power to deliver on the president-elect’s top priorities, including a tax bill, government spending, and border security, among other policies.

The new chairmen are selected by the House GOP Steering Committee, a panel of over 30 Republican leaders and regional representatives that recommend the committee chairs for approval from the full Republican conference.
