Hearings on the crisis are imminent, and could even result in the impeachment of Alejandro Mayorkas, the Secretary of Homeland Security. Earlier this week, Republican lawmakers filed a resolution to have Mayorkas impeached, their second attempt to do so less than one month into the new Congress.
In a press release announcing the move, the resolution's sponsor Republican Andy Biggs described Mayorkas as the "chief architect of the migration and drug invasion at our southern border."
A cabinet member hasn't been impeached since William Belknap in 1876 (Belknap, who served as secretary of war, was later acquitted), and the move would be a serious blow to the Biden administration.
That said, Mayorkas has little chance of being convicted by the Democrat-controlled Senate and critics have derided the proceedings as a waste of both time and energy.
