The fall of Kabul on Aug. 15, together with the subsequent chaotic evacuation of U.S. citizens and the deaths of at least 13 U.S. service members in a terrorist attack outside the city’s airport on Aug. 26, has triggered a wave of outrage among lawmakers, with numerous Republicans going beyond mere criticism of the Biden administration’s drawdown of U.S. troops to say that the president ought to vacate office.

The invocation of the 25th Amendment, resignation, and impeachment have all been promoted in recent days as possible solutions by a growing number of Republican officials, who say Biden’s actions since Afghanistan fell to the Taliban call into question the president’s fitness to serve.
