The Cincinnati Tea Party will offer refunds after Fox News host Sean Hannity pulled out of an appearance at its Tax Day rally — a cancellation that the group said has not been fully explained.

"We've offered refunds. Although it was not our error, we felt it was the right thing to do for the attendees," Cincinnati Tea Party spokesman Justin Binik-Thomas told TVGuide.com.

Binik-Thomas said more than 10,000 people turned out for Thursday's rally at the University of Cincinnati, which was going to be preceded by a book-signing by Hannity and followed by the taping of his show on campus. Biniki-Thomas said he was told Hannity had to return home to New York for a personal emergency after the book-signing was abruptly canceled.

"They were completely separate events. They chose not to come. That was their decision. It did not impact our event," he said. "We had 10,000 people come together celebrate the liberty and the freedom that we have and our core values. Our event was very positive."

Despite the cancellation, Binik-Thomas said he's not angry with Fox News or Hannity. "It's their decision to make, not mine, and they can spend their money and their personnel as they see fit. I don't hold a grudge," he said. "People came for the tea party and anything Hannity-related was a bonus."

Calls and e-mails to Fox News were not immediately returned.
