In a much publicized climax of a rousing speech on gun control, Joe Biden said "God save the Queen, man".
Bizarre.
My pshat: Joe sees himself as King and Rebbetzin Jill as Queen. I mean, America doesn't really have a King and Queen so they are closest thing to it. So it was a bracha and show of respect to his wife.
