PHOENIX - Maricopa County Sheriff Joe Arpaio says there are indications of fraud regarding President Barack Obama's birth certificate and selective service card.
Arpaio said at a 1 p.m. news conference that there is "probable cause to believe forgery and fraud occurred."

Arpaio scheduled the news conference Thursday to unveil preliminary results of an investigation, conducted by members of his volunteer cold-case posse, into the authenticity of Obama's birth certificate, a controversy that has been widely debunked but which remains alive in the eyes of some conservatives.
Mike Zullo, lead investigator with the department's cold case posse presented detailed evidence backing up the sheriff's claim.
"We do not have a single document that proves Mr. Obama's birth in Hawaii or anywhere in the United States for that matter," Zullo said. "The document is fake, the representation is fake.
"We believe this should be a full blown investigation," Zullo said.
Authorities have an investigative lead into the forgery, he said, but would not elaborate.
"It is built, manufactured by layers," Zullo said. "We would like to find the person who pushed the upload button."
"If nothing else comes out of the investigation …what we have learned, we need a better process to vet people running for president of the United States of America," Arpaio added.
"Do I just throw it in the wastebasket and just forget it … when you say that 50 states have looked at this, okay, show me how far they went…and don't go telling me I'm the only one looking into this," he said.
Arpaio said the investigation did not cost the taxpayers a penny. He said he hasn't decided where he will go with the results, saying it's a tough decision; whether to ask for congressional hearings or a federal investigation, beginning in Hawaii.
Zullo said the investigation is ongoing.
Last year, Donald Trump most prominently revived the issue while entertaining a possible bid for the presidency.
The 79-year-old Republican sheriff defends his need to spearhead such an investigation after nearly 250 people connected to a Surprise, Ariz. tea party group requested one last summer.
"I'm not going after Obama," said Arpaio, who has criticized the president's administration for cutting off his federal immigration powers and conducting a civil rights investigation of his office. "I'm just doing my job."
Some critics suggest Arpaio's aim is to divert attention from his own legal troubles while raising his political profile as he seeks a sixth term this year. The sheriff vehemently denies such strategies are in play.
"I don't need this for politics, I guarantee," Arpaio said during the news conference.
The White House said it had no comment to today's allegations and referenced a statement released last year regarding the issue.
Democratic state Sen. Steve Gallardo said Arpaio is pandering to relentless critics of the president.
"It doesn't matter what President Obama does, they'll never support him," Gallardo said. "It's those folks who will continue to write checks to Sheriff Joe because of this stuff."
Arpaio's probe comes amid a federal grand jury investigation into the sheriff's office on criminal abuse-of-power allegations since at least December 2009, focusing on the sheriff's anti-public corruption squad.
Separately, the U.S. Justice Department has accused Arpaio's office of racially profiling Latinos, basing immigration enforcement on racially charged citizen complaints and punishing Hispanic jail inmates for speaking Spanish. Arpaio denies the allegations and said the investigation is politically motivated.
Critics also have sought Arpaio's resignation for more than 400 sex-crimes cases over a three-year period ending in 2007 that were either inadequately investigated or weren't investigated at all by the sheriff's office after the crimes were reported. The sheriff's office said the backlog was cleared up after the problem was brought to Arpaio's attention.
Speculation about Obama's birthplace has swirled among conservatives for years. "Birthers" maintain that Obama is ineligible to hold the country's highest elected office because, they contend, he was born in Kenya, his father's homeland. Some contend Obama's birth certificate must be a fake.
Hawaii officials have repeatedly confirmed Obama's citizenship, and Obama released a copy of his long-form birth certificate in April in an attempt to quell citizenship questions. Courts also have rebuffed lawsuits over the issue. Of late, the president's re-election campaign has poked fun at it, selling coffee cups with a picture of the president's birth record.
Arpaio has said he took deliberate steps to avoid the appearance that his investigation is politically motivated. Instead of using taxpayer money, the sheriff armed it out to lawyers and retired police officers who are volunteers in a posse that examines cold cases. Other posses assist deputies in duties that
