Dan Abrams pinned one of his guests last night. Rep. Jack Kingston was on to discuss his questioning of Sen. Barack Obama's patriotism. Last Friday on Real Time with Bill Maher, Kingston questioned why Obama refuses to wear an American flag lapel pin. During the interview, Abrams noticed the congressman was not wearing a flag pin either.

Abrams: "You're not wearing a lapel pin, are you?"

Kingston: "I will wear one and I have worn one, but I'm not making a statement about it."

Abrams: "But do you see my point? I mean, I had no idea that you were going to show up without a lapel pin. But it seems kind of absurd that you're saying Barack Obama's patriotism should be questioned because he's not wearing a lapel pin, and then you come on this show not wearing one!"

That was just the beginning. Has Abrams ever worn an American flag lapel pin? Has Sen. John McCain ever been photographed without an American flag lapel pin? Answers to these questions and more in the full video of the interview, after the jump...
