PHOENIX-- A bill that would require presidential candidates to prove they are natural born citizens before being listed on the ballot cleared the Arizona State Senate Wednesday.
House bill 2177 passed the Senate 20 to 9 and now goes back to the House for a final vote.
Anthem House Republican Carl Seel authored the bill and says the intent is to "maintain the integrity of the Constitution."
The bill would require presidential candidates to submit a long form birth certificate that includes at least the date and place of birth, the names of the hospital and doctor, and, if applicable, signatures of any witnesses in attendance.
If a long form birth certificate is not available, other documents will be required.
The "birther" issue has gained traction nationally in recent weeks as possible-presidential candidate Donald Trump has made repeated calls for President Obama to reveal his birth certificate.
Phoenix Democrat Senator Kyrsten Sinema voted against the bill and says it has no standing in federal or state law.
"This is designed specifically to challenge [Obama's] ability to run for re-election," said Sinema. "Frankly, I think they'd be better served by just surfacing a good candidate to run against him."
