(CNN) - White House aides are scoffing at a move in the Arizona legislature to force President Obama to show his birth certificate to get on the state's ballot in 2012 for his likely re-election battle.
"This is a question that has been answered exhaustively," White House spokesman Bill Burton told CNN. "I can't imagine Arizona voters think their tax dollars are well served by a legislature that is less focused on their lives than in fringe right-wing radio conspiracy theories."
The Arizona House voted Monday by a 31-22 margin to require all presidential candidates to prove they were born in the United States in order to meet the constitutional requirement. The measure still has to be considered by the Arizona state Senate before it can become law.
When the issue first popped up during the 2008 presidential election, the Obama campaign released the then-senator's birth certificate showing that he was born in Hawaii. In December 2008, after Obama was elected, the U.S. Supreme Court turned down an emergency appeal from a New Jersey man claiming Obama was ineligible to serve as president.
