Rosie O’Donnell fired right back at Donald Trump after he threatened to revoke her U.S. citizenship in a post on Truth Social on Saturday morning.

The comedian and former talk show host, a longtime critic of the president, was — like Trump — born in New York to one American-born parent and one immigrant parent.

In a blistering response to his threat, she called him “King Joffrey with a tangerine spray tan,” a reference to a much-hated, sadistic, authoritarian character from Game of Thrones.
