'Birther' talk to stay as Arizona passes bill, Palin rejoins debate

The Arizona state Senate passed a bill on Wednesday that makes it mandatory for presidential candidates to produce documents proving that they are citizens of the United States.

The controversial bill, which the Democrats say is outside the scope and authority of the state, says future presidential candidates will not be included on the state's ballot unless they prove their citizenship.

Presidential aspirants can either produce a long form birth certificate, a baptismal certificate or a circumcision certificate to prove their citizenship, the bill says.

Carl Seel, the Republican Senator who introduced the bill, had met with billionaire real estate developer and possible presidential candidate Donald Trump late last week.

Trump brought back to national stage the debate surrounding President Barack Obama’s birth certificate long after the Tea Party had let the issue die down.

Trump, who has surged into the frontline of possible Republican candidates to challenge Obama in the 2012 run, has insisted that he isn’t satisfied with the proof the President has provided to prove that he was born in Hawaii.

If you go back to my first grade, my kindergarten, people remember me. Nobody from those early years remembers him... If you're going to be president of the United States, it says very profoundly you have to be born in this country, Trump said in a CNN interview.

Prompted by Trump's dramatic rise in poll ratings, former Republican vice-presidential candidate Sarah Palin too has rejoined the 'birther' debate, saying there is something the President doesn’t want people to see.
