At a Television Critics Association panel for the ninth series of Curb, as the show is known to fans, Mr David confirmed the link.
"He's in the line... like a third cousin, or something”, he said.
"I was very happy about that, I figured there was some connection."

“How many pairs of underwear do I have? Am I really Larry David?” the candidate said, to laughter from the audience.
Well, it turns out that the actor and senator are part of the same mishpacha – and a very hearty mazel tov to them both!
