MSNBC's Chris Matthews got into a heated exchange with a congressman on his show Tuesday as he revisited the question of President Barack Obama's birth certificate — or lack of one.

Rep. John Campbell, R-Calif., is a co-sponsor of the so-called "birther bill," which would require future presidential candidates to provide a copy of their original birth certificates.

“Birthers” are those who believe Obama is not qualified to be president, based on a belief that he was not born in the United States.

Campbell is not a “birther” and never has claimed that Obama was born outside the United States or should be disqualified from being president.

On the show, Matthews seemingly undermined claims by some that Obama never has released his birth certificate, producing what Matthews said was a true copy of it.

But Matthews made a false claim. Obama never has released his actual birth certificate. He has released another document, which state authorities often provide in lieu of a birth certificate, called a certification of live birth.

Matthews on Tuesday said Campbell was "playing to the crazies" by supporting the "crazy" bill, and the congressman shot back that it was all about "putting the matter to rest."
