Investigators in Arizona are calling out President Barack Obama, saying that the birth certificate released by the White House in April 2011 is definitely fraudulent.

Maricopa County Sheriff Joe Arpaio, the man who is spearheading the investigation, said in March that he believed there was probable cause that Obama's long-form birth certificate was a product of computer-generated forgery.

Five months later, Arpaio has released the results of his investigation and is pointing out specific inconsistencies on Obama's birth certificate.

The Associated Press is reporting that Mike Zullo, Apraio's chief investigator, said numeric codes on certain parts of the birth certificate indicate that those parts weren't filled out, yet those sections asking for the race of Obama's father and his field of work or study were completed.

Zullo reportedly went on to say that while investigators previously didn't know the meaning of codes, they were eventually explained by a 95-year-old former state worker who signed the president's birth certificate. In addition, said a writer who published a book about Obama's birth certificate and was aiding investigators let them listen in on an interview he conducted of the former state worker.

While the investigation might seem like an effort to smear president Obama's  credibility, The Arizona Democratic Party said in a statement that Arpaio's investigation is intended to draw attention away from problems within his own agency, such as hundreds of sex-crime cases that the sheriff's office failed to adequately investigate over a three-year period.

In an apparent reinforcement of the Obama's questioned citizenship, Hawaii officials have repeatedly confirmed Obama's citizenship, and state officials did again Tuesday.

President Obama was born in Honolulu and his birth certificate is valid, Joshua A. Wisch, a special assistant to Hawaii's attorney general, said in a statement obtained by AP. Regarding the latest allegations from a sheriff in Arizona, they are untrue, misinformed, and misconstrue Hawaii law.

According to the newswire, Wisch also said that not only are Hawaii's vital records some of the best managed, but they also have some of the strongest restrictions on access to prevent identity theft and fraud.

As Obama's birth certificate has long been a topic of national debate, courts have rebuffed lawsuits over the issuem.
