Since President Donald Trump announced on Tuesday the surprise arrest of a man accused of taking part in the killing of 13 U.S. service members in Afghanistan, his top national security aides have repeatedly disparaged the Biden administration as either unwilling or unable to bring those responsible to justice.

In a speech to Congress, President Donald Trump announced the apprehension of the person he said was the “top terrorist” responsible for the attack that killed 13 U.S. service members in August 2021.

The bombing, which mired the Biden administration, occurred just days before the U.S. military withdrew from Afghanistan, ending its 20-year war.
