Bernie Sanders’ former press secretary mocked Joe Biden on Monday, calling him “king of the Black people” and asking why he hasn’t “put an end” to riots. “The way the press talked about him, you’d think one statement from Biden, king of the Black people, could put an end to all this,” Briahna Gray on Twitter. “Wonder why it hasn’t worked.” Gray has repeatedly lambasted Biden since Sanders suspended his campaign. She called sexual assault allegations against the presumptive Democratic nominee “credible” and said the media has never focused on his “vulnerabilities.”
