GOP senators are reaching out to House Speaker John Boehner to stop President Obama from appointing Elizabeth Warren as head of the CFPB.

“Given President Obama’s indifference to the Senate’s constitutional authority, and the American people’s right to scrutinize his appointees through regular order of advise and consent, we urge you to refuse to pass any resolution to allow the Senate to recess or adjourn for more than three days for the remainder of the president’s term,” the senators said in a letter to House Speaker John Boehner (R., Ohio).
