The former six-term congressman stepped down Friday as host of his conservative talk radio program on a radio station in Phoenix.
"We will formally announce at a later time, but we're moving forward to challenge John McCain," Hayworth told the Associated Press. "I think we all respect John. I think his place in history is secure. But after close to a quarter-century in Washington, it's time for him to come home."
Shiree Verdone, McCain's campaign manager, said in a statement, "Senator McCain has always taken every challenge seriously, and is confident with the help and support from the people of Arizona that he will be re-elected to the United States Senate."
Hayworth would not have been able to continue hosting a radio program and also legally run for federal office. Hayworth was ousted from Congress in the 2006 election and has hosted the radio show for the past few years.
"It has been a joy to spend weekday afternoons on KFYI. Now, another chapter begins. The call to public service remains, and again it may very well lead to pursuit of public office," Hayworth said in a statement posted on the radio station's website.
Hayworth told AP that a recent "outpouring of support" from people in Arizona asking him to run changed his mind about challenging McCain, the 2008 GOP presidential nominee and four-term senator who's up for re-election this year.
McCain's already facing a primary challenge from Chris Simcox, a co-founder of the Minuteman movement. Simcox announced his candidacy last April and then resigned from the volunteer organization, which tries to prevent illegal crossings of the U.S. border. McCain's past support of immigration reform legislation in Congress nearly derailed his presidential bid two years ago.
Wednesday McCain's running mate in 2008, former Alaska Governor Sarah Palin, announced she would travel to Arizona to campaign with McCain in March. Palin is very popular with many voters on the right, and her teaming up with McCain could help him with some Republican voters who question his commitment to conservative values and goals.

He is old school.He votes NO on every bill.
I can't believe it's possible that the State of Arizona can't – or won't -come up with a better candidate that J.D. Hayworth.. Your state is beginning to remind me of South Carolin EGADS!.
Excellent! It's about time a real conservative occupied the seat that McCain's been occupying for far too long. I for one have had enough of the liberal nonsense coming from the ENTIRE McCain family.
It's high time that the conservative principles of Barry Goldwater returned to Arizona's place in the U.S. Senate!
Say 'hello' to the unemployment line, Johnny...
OBAMA will be our president come 2013.Americans should sop listening to GPO,the party for" NO" on everything.
What a truly sad situation to have these two choices.McCain is way past reality and for making the worst running mate decision ever, he will not be forgiven. Once you have been on the right wing radio circut , that should be the end of your political career. Hayworth took the bottom of the barrel radio show and to me that makes him un electable.I have realitives in Arizona and feel sorry for them in regards to these two horrible choices
Go JD. We need to run the progressive lite McCain out of office
Palin would much prefer supporting Hayworth than McCain. McCain better be careful because Palin could easily screw up her lines and endorse Hayworth by mistake.
All poloticians should be limited to two terms. One in office and the other in prison for what they have done to this nation. They seem to forget that they work for the people and not themselves.
