That would be his brother, Chicago Mayor Rahm Emanuel, who made some jokes at his borther’s expense at the opening of the 2011 Cable Show.
“On behalf of the entire Emanuel family, we apologize for Ari,” said Emanuel, per the Los Angeles Times. “You know him as an agent, we know him as a brother. We thought that we got the worse end of the deal.”
He was kidding, of course, but it makes me remember all of the jokes from President Obama about Rahm’s penchant for expletives.
