ONEONTA, Ala. (AP) — The state of Alabama has apologized to a gun store owner for trying to take away a personalized license plate representing an obscene slur against President Joe Biden.

Nathan Kirk says he received a letter from the Alabama Department of Revenue stating that he can continue using the plate on his pickup truck.

Kirk’s plate includes the acronym “LGBF JB” — a reference to a political chant and a vulgar insult of Biden. But Kirk says the state can’t prove the “F” stands for an obscenity.

The state’s reversal came after the tag became a topic on social media and right-wing media outlets.
