Republicans universally agree that President Joe Biden's bungled handling of the Afghanistan pullout has given them fresh ammunition to attack the commander in chief. Many Democrats think the same. But a major rift is starting to emerge in GOP messaging, as the Donald Trump wing of the party seeks to turn the matter into a base appeal with anti-immigration rhetoric.

Over the past week, most GOP lawmakers have lambasted Biden for abandoning interpreters and Afghan civilians who put their lives at risk to help U.S. troops — and are now trapped as armed militias block their escape.

But a not-insignificant chunk of the party is using the Afghanistan disaster as fodder for their campaign against immigration. The unsubstantiated charge: that Biden intentionally fumbled the withdrawal in order to flood the U.S. with Afghans.
