The union representing the nation’s border patrol agents jumped on social media during Thursday night’s CNN debate to refute President Joe Biden’s claim that border agents endorse him, not his opponent, former President Donald Trump.

“By the way, the Border Patrol endorsed me,” Biden claimed while attempting to excuse his administration’s handling of the illegal immigration crisis at the U.S. southwestern border.

“To be clear, we never have and never will endorse Biden,” the Border Patrol Union quickly responded on social media.
