A bill that would require candidates to prove they are natural born U.S. citizens before qualifying for the Louisiana ballot wasn't Republican Gov. Bobby Jindal's idea but he will gladly endorse it if he gets the chance.

Jindal press secretary Kyle Plotkin told The Times-Picayune Tuesday that the governor will sign the so-called "birther" bill if it reaches his desk.

"It's not part of our package, but if the Legislature passes it we'll sign it," Plotkin said.

Two Republican lawmakers, state Rep. Alan Seabaugh and state Sen. A.G. Crowe, introduced House Bill 561 last week. It would require birth certificates for all federal candidates who want to be on the state ballot.

Arizona Gov. Jan Brewer (R) vetoed a similar bill Monday that would have required presidential candidates to prove they are natural born American citizens before their names can appear on the state's ballot.

"I never imagined being presented with a bill that could require candidates for President of the greatest and most powerful nation on earth to submit their 'early baptismal or circumcision certificates,'" Governor Jan Brewer said. "This is a bridge too far. This measure creates significant new problems while failing to do anything constructive for Arizona."

House Bill 2177 would have required presidential candidates to submit a certified copy of their birth certificate that includes their date and place of birth, the names of their mother and father, and the name of the hospital where they were born. In addition, candidates could provide other documents, early baptismal or circumcision certificates, to prove they were natural born citizens.

The Arizona Senate passed the bill in a party-line vote of 20 to 9, with Republicans backing the bill, and was approved by the state House in a 40-16 vote.

The Arizona Legislature will now have the opportunity to override Brewer's veto.
