Since Joe Biden’s earliest days in the Oval Office, some House Republicans have sought to remove the President and his Cabinet members from office. Last week, the Homeland Security Secretary, Alejandro Mayorkas, was impeached—on a second attempt—by a slight margin, in regard to the Biden Administration’s handling of the U.S.-Mexico border crisis. Meanwhile, the House’s other impeachment investigation, into Biden, is on the verge of collapse, after its star witness was charged with providing false information about Biden and his son Hunter to F.B.I. agents. The F.B.I. informant also, by his own account, has ties to Russian intelligence agencies. The ubiquity of impeachment cases today signal a change in our politics. “What was once a pretty rare and solemn instrument of accountability now looks more and more like just another partisan tool,” the staff writer Evan Osnos says. The New Yorker staff writers Susan B. Glasser and Jane Mayer join him to weigh in.
