Cain spoke with 'two of the top' GOP candidates about endorsement

Cain also clarified that his announcement that he was "suspending" his campaign means that he is definitively leaving the race for the White House.

"It means end," Cain said. "There are no plans to re-emerge — if I want to re-emerge, the spin would begin again."

The "spin" Cain refers to involves the swirling allegations of sexual impropriety, including multiple women who accused Cain of sexual harassment during his time as president of the National Restaurant Association, and claims by an Atlanta businesswoman of a prolonged extramarital affair.

Cain said he believed the accusations were the result of a conspiracy to knock him out of the race.

"I am convinced that the way that it was done, the fact that they went after my character and they knew that it would hurt my family," Cain said.

He also stated that believed accusers would continue to emerge — not because the allegations were true, but out of a determination by opponents to hurt his campaign.

"We also knew that because somebody was so determined to knock me out of the race, that there are probably going to be more [accusations] down the road," Cain said.

But, Cain said, he was planning further action to prove his innocence.

"Without compromising anything my attorney and I are working on, we're not done proving or demonstrating," Cain said.

The former Godfather's Pizza CEO also emphasized that he left the race solely because of the toll the stories were taking on his wife, and not as an admission of guilt.

"I saw the pain that it was causing my wife, and I wasn't going to let it happen," Cain said.

Still, he admitted that the decision was a difficult one.

"It was hard primarily because of all of the supporters that i had gotten; I knew it was going to be disappointing to a lot of people, and I personally was disappointed," Cain said.

Nevertheless, Cain also hinted at plans to possibly launch a radio or television show. Many of the Republican candidates from the 2008 race went on to sign contacts with Fox News, a point alluded to by host Sean Hannity.

Cain said he wanted to "create the biggest platform" to spread his message and "change Washington from the outside."
