HONOLULU -- A privacy law that blocks the release of birth certificates has prompted Hawaii's Democratic governor to end his efforts to dispel claims that President Obama was born outside of the state, his office said.

State Attorney General David Louie told the governor that privacy laws bar him from disclosing an individual's birth documentation without the person's consent, Gov. Neil Abercrombie's spokeswoman Donalyn Dela Cruz said Friday.

"There is nothing more that Gov. Abercrombie can do within the law to produce a document," said Dela Cruz. "Unfortunately, there are conspirators who will continue to question the citizenship of our president."

Abercrombie, who was a friend of Obama's parents and knew him as a child, launched an investigation last month into whether he can release more information about the president's Aug. 4, 1961 birth. The governor said at the time he was bothered by people who questioned Obama's birthplace for political reasons.

But Abercrombie's attempt reached a dead end when Louie told him the law restricted his options.

Hawaii's privacy laws have long barred the release of a certified birth certificate to anyone who doesn't have a tangible interest.

So-called "birthers" claim Obama is ineligible to be president because they say there's no proof he was born in the United States, with many of the skeptics questioning whether he was actually born in Kenya, his father's home country.

Hawaii's health director said in 2008 and 2009 that she had seen and verified Obama's original vital records, and birth notices in two Honolulu newspapers were published within days of Obama's birth at Kapiolani Maternity and Gynecological Hospital in Honolulu.

Health Department spokeswoman Janice Okubo again confirmed Friday that Obama's name is found in its alphabetical list of names of people born in Hawaii, maintained in bound copies available for public view.

That information, called index data, shows a listing for "Obama II, Barack Hussein, Male," according to the department's website.

"The index is just to say who has their records within the department. That's an indication," Okubo said. "I can't talk about anyone's records."

In 2008, the Obama campaign issued a certification of live birth, a non-legal document that shows the president's birth date, city and name, along with his parents' names and races. This was a computer-generated document, and not the original birth certificate.
