President Donald Trump called Virginia Gov. Ralph Northam “unforgivable” on Saturday, responding to the controversy over a racist photo from the Democrat’s medical school yearbook.

After previously admitting to appearing in the image, which showed a man in blackface next to another clad in a Ku Klux Klan hood, Northam backpedaled during a press conference, claiming he actually wasn’t in the photo.

Trump called out Northam on Twitter, writing the reversal occurred “24 hours after apologizing for appearing in the picture.” He also bashed the governor over his recent remarks on a bill in the Virginia state legislature that sought to lift abortion restrictions.
