(CNN) – Former Rep. J.D. Hayworth is putting to rest any notion that he is a "birther," a believer in the unsubstantiated theory that President Obama is not a natural born U.S. citizen and, therefore, not eligible to be president of the United States.
At a press conference Monday, the former congressman was repeatedly asked about recent comments which appeared to suggest he believes Obama was not a citizen.
"I believe that Barack Obama is an American citizen," Hayworth said.
After several questions Hayworth added, "Barack Obama is the president of the United States."
Hayworth is challenging Arizona Sen. John McCain in this year's Republican primary..
Last week in an interview with CNN's Campbell Brown, Hayworth raised the issue of identity theft as one reason some members of the public might be concerned about Obama proving he is a U.S. citizen. Hayworth was responding to Brown's query about comments he'd made in late January where he called on Obama personally to produce a birth certificate instead of relying on the State of Hawaii to do so.
In his Monday news conference, Hayworth, who recently left a stint as a conservative radio talk show host, said his earlier comments about Obama's citizenship had been inspired by his time working in radio.
"I was talking in another context about what I was hearing on the radio," Hayworth said.
He added, "To bring up a topic and to talk about it is not the same as endorsing a point of view."
Hayworth also took the opportunity Monday to accuse McCain, of being a flip-flopper on the Wall Street bailout.
McCain, the 2008 GOP presidential nominee, recently told the editorial board of The Arizona Republic that he had been misled by then-Treasury Secretary Henry Paulson and Federal Reserve Chairman Ben Bernanke about "TARP" otherwise known as the Troubled Asset Relief Program.
"And now it seems that [McCain] would have us believe that he would change positions on that vote [for TARP]," Hayworth said.
"That type of flip-flop is more reminiscent of John Kerry than the John McCain with whom I worked for so many years," Hayworth also said, making a reference to the 2004 Democratic presidential nominee who was attacked by the GOP as a flip-flopper.
McCain's re-election campaign quickly fired back at Hayworth.
"Senator McCain has long questioned the management of TARP, declared that the funds were being misused and voted repeatedly to defund it," McCain campaign Communications Director Brian Rogers said in a written statement.
