Kentucky Senate candidate Rand Paul says he'll decide Friday whether to take part in a final political debate next week following a campaign ad by his opponent that questions his religious beliefs.

Democratic opponent Jack Conway recently released an ad that accuses Rand of making fun of Christians at Baylor University 30 years ago. The ad goes on to claim that Paul was part of a society that called the Bible "a hoax," and warned he will end all faith-based initiatives.

Paul said the accusations are completely untrue, and at a press conference Thursday, asked the media why he has to respond to a story from decades ago, made on the Internet by an anonymous source.

"Is no one else appalled that hearsay and gossip would be reported as fact? I'm still appalled that your newspaper and others in the state printed anonymous accusations and your justification is, "Oh, it was printed somewhere else,'" Paul charged. "Is that the standard that we've come to that if someone prints something on the Internet, you're allowed to print it in your newspaper?"

"I mean, an anonymous accusation that goes to someone's character has no place in political discourse," he continued. "And people who print it should be ashamed, and people who recite it should be ashamed."

Paul has called on Conway to apologize for the ad.
