PHOENIX -- Sheriff Joe Arpaio of Arizona has fixated on the authenticity of President Barack Obama’s birth certificate for more than five years, going so far as to send a deputy and member of his volunteer posse to Hawaii to question officials.
He earned plaudits from Donald Trump and became one of the nation’s leading voices on the debunked controversy over Mr.Obama’s birthplace. Arpaio plans to close his yearslong investigation Thursday, ending a chapter that critics denounced as a shameless ploy to raise money from his right-wing base.
The news conference from the media-savvy sheriff comes three weeks before the end of his 24 years as metro Phoenix’s top law enforcer and five weeks before Mr. Obama leaves office.
“We and anyone else who dared to question the document have been maligned, falsely labeled and grossly criticized,” Arpaio said, refusing to take questions from reporters.
The sheriff took up the “birther” mantle as he faced some of his worst legal troubles, including a racial profiling case that discredited his patrols targeting immigrants and a grand jury inquiry into his failed investigations of local political enemies.
He refused to back away from the investigation three months ago when Mr. Trump, an Arpaio ally, relented on his claim that Mr. Obama wasn’t born in the U.S.
Maricopa County Supervisor Steve Gallardo, a longtime Arpaio critic, said the investigation was a publicity stunt to raise the sheriff’s national political profile and bring in campaign dollars.
“He was trying to throw meat to his base, and that’s exactly what he did,” Gallardo said. “He threw red meat.”
At the news conference Thursday, Arpaio said the investigation was never about where President Obama was born,CBS affiliate KPHO reported.
“To this day I stated that I did not care where the president was born,” said Arpaio. “We were going to investigate a government possible forged document.”
“Today we’re going to set the record straight,” said Arpaio. “I believe you will be shocked by what you hear today. The implications will be profound.”
Arpaio wasn’t the only Arizona politician to plunge into the erroneous effort.
The Arizona Legislature passed a bill in 2011 that would have required Mr. Obama and other presidential candidates to prove they were U.S. citizens before their names could appear on the ballot. It was vetoed by the GOP governor.
Several Electoral College members even questioned Mr. Obama’s eligibility to serve as president as they cast their votes for Republican Mitt Romney four years ago.
Arpaio has said he launched the probe after nearly 250 people connected to an Arizona tea-party group requested it. He pressed forward despite aides warning he would be ridiculed.
In the 2014 documentary “The Joe Show,” Arpaio was seen brushing aside his publicist’s prediction that he would be viewed as a clown. The sheriff said the investigation would help his fundraising efforts.
“It may look nuts, but you know what, it’s going to be pretty good,” Arpaio said.
The sheriff won praise several months later in a tweet from Mr. Trump: “Congratulations to RealSheriffJoe on his successful Cold Case Posse investigation which claims BarackObama’s ‘birth certificate’ is fake.”
Arpaio farmed out the investigation to volunteers on his posse, which is funded through donations, in anticipation of criticism he was throwing away taxpayer money.
In 2012, he said the investigation revealed that there was probable cause to believe Mr. Obama’s long-form birth certificate was a computer-generated forgery and that the selective service card completed by Mr. Obama in 1980 was likely a fraud.
The facts say otherwise. Hawaii officials repeatedly confirmed Mr. Obama’s citizenship, and the courts rebuffed a series of lawsuits.
Arpaio insisted he wasn’t investigating whether Mr. Obama was a U.S. citizen but examining an allegation that the document was fraudulent. But critics say it was a calculated swipe at the identity and legitimacy of the nation’s first African-American president.
Though Arpaio promised no taxpayer money would be spent on the investigation, the sheriff sent a deputy to Hawaii to accompany the posse’s top investigator. The sheriff said the posse would reimburse his office for the costs of the deputy’s travel and time.
At one time, Arpaio said the posse spent $40,000 in donations on the investigation. It’s not known how much it ultimately cost and whether the agency was reimbursed.
