In the very last hours of President Joe Biden’s time in office, a prisoner exchange years in the making was finally struck: the Taliban agreed to swap two Americans being held in Afghanistan for one Taliban member serving a life sentence in a US prison.

Americans Ryan Corbett and William W. McKenty III were freed, their families said. The Taliban said Khan Mohammed, an Afghan serving a life sentence in California, was released.

The last-minute deal was the final capstone in Biden’s campaign to release dozens of Americans detained abroad.
