Rep. Pat Fallon (R-TX) has introduced articles of impeachment against Department of Homeland Security Secretary Alejandro Mayorkas. Driving the news: Newly-elected House Speaker Kevin McCarthy had previously threatened a potential “impeachment inquiry” into Mayorkas over the DHS secretary's handling of the U.S.-Mexico border if Mayorkas didn't resign — a nod to the GOP conference’s right flank that ultimately undermined his speakership bid.
