Jacksonville, Florida (CNN) - For days, supporters of Mitt Romney have trailed Newt Gingrich across Florida, hoping to rattle the former House speaker and occasionally clashing with his spokesman.
On Monday, a Gingrich supporter decided to return the favor.

Rick Tyler, a former Gingrich aide and the spokesman for Winning Our Future, a super PAC supporting the former speaker's candidacy, stood in the back of a Romney rally in Jacksonville and broadcast his criticism of the GOP candidate to anyone who would listen.
"I'm here to get as many cameras and microphones so I can talk about Mitt Romney's incessant failure to tell the truth," Tyler told members of the media standing fifty feet away from Romney, who was greeting supporters after his rally. "I thought, well no one said I couldn't go to a Romney event, so here I am."
"I couldn't keep up with the lies," Tyler continued. "I mean, Mitt Romney seems to have a congenital defect. He can't distinguish the truth from a lie and that's evident in his ads, it's evident in his speeches."
Federal election law prohibits a super PAC from coordinating with a campaign on strategy.
Throughout the event, Tyler used Twitter to take on what he called "lies" in Romney's speech, and mocked the candidate when an introducer awkwardly tried to stall while waiting for Romney to join him on stage.
Tyler tweeted: "Romney late to first event. Intro guy ran out of positive things to say about Mitt. Taking song requests."
The introducer, Rep. Ander Crenshaw, was leading the audience in a rendition of "God Bless America."
Tyler said he would continue to attend Romney's events and criticize the GOP candidate's record.
A Romney spokesman did not immediately respond to a request for comment.
For his part, Romney kept up his attacks on Gingrich on stage, mocking the former speaker for proposing to build a moon base during his presidency.
A member of the audience shouted of Gingrich: "Send him to the moon!"
Romney acknowledged the quip, and added: "The idea of the moon as the fifty-first state is not what would have come to my mind as a campaign basis here in Florida."
