President Biden on Sunday remarked that he was involved in the civil rights movement during a speech in Selma, Alabama – a claim that remains unproven.

The president visited the historic city to commemorate the 58th anniversary of the "Bloody Sunday" march, a pivotal moment of the 1960s civil rights movement.

"I was a student up north in the civil rights movement," Biden said to the crowd. 

"I remember feeling how guilty I was, [that] I wasn't here. How could we all be up there, and you going through what you went through," he continued.

But there is no historical evidence to support Biden's claim. Sunday's speech was not the first time Biden has claimed to be involved in the civil rights movement.
