Gov. Chris Christie was interrupted by hecklers during a speech at campaign rally in Iowa yesterday for Republican presidential hopeful Mitt Romney.

The governor fired back at the hecklers saying, "You know we are used to dealing with jokers like these all the time in Jersey don't you worry about it."

The appearance came less than four weeks before the Iowa caucus. Christie endorsed Romney in October, soon after he announced that he would not run for president himself despite being urged to do so by some major fundraisers.
