In an appearance on Sean Hannity's show tonight, Newt Gingrich described Occupy Wall Street as a threat to free speech while discussing being interrupted by protesters on the campaign trail. Mr. Gingrich canceled a scheduled appearance in New Hampshire today due to concerns over the protesters.

"Some of the Occupy Wall Street people frankly have a touch of anarchism in them. I think, ultimately, the society's going to have to say there are limits to those kind of folks blocking people from having their right to free speech," Mr. Gingrich said. "We decided it wasn't worth risking some kind of big confrontation, so we, frankly, decided to skip past that particular event."

Mr. Hannity originally thought Mr. Gingrich had an issue with Ron Paul supporters. Mr. Gingrich set the record straight.

"I think our challenge was with Occupy Wall Street people, I've generally found that the Ron Paul people, while theyre sometimes noisy, they're pretty civil and pretty decent," said Mr. Gingrich.

Occupy protesters have disrupted events hosted by several 2012 candidates including Mitt Romney and President Barack Obama.

Mr. Gingrich said the Republican candidates shouldn't stand for these disruptions any longer.

"I do think that we can't be held hostage by those kind of people," Mr. Gingrich said.
