GAINESVILLE, Fla. -- The University of Florida student who spent a night in jail after being Tasered and arrested at a question-and-answer session with Sen. John Kerry, D-Mass., is now free.

Andrew Meyer was released Tuesday morning on his own recognizance. He had no comment as he left the jail in Gainesville.

Video of the incident last night shows officers pulling Meyer away from the microphone, after he loudly and repeatedly tried to ask Kerry about impeaching President George W. Bush, and about whether he and Bush were both in the secret Skull and Bones society at Yale.

Jail records show he was arrested on charges of resisting an officer and disturbing the peace.

Details from Meyer's online writings and videos also raised the question of whether his harangue was genuine.

Meyer has a Web site featuring several homemade videos. In one, he stands in a street with a sign that says "Harry Dies" after the latest Harry Potter book was released. In another, he acts like a drunk in a bar while trying to pick up a man dressed in drag.

The university's president said he's asked state authorities to investigate the arrest. Officials say the probe will determine whether appropriate force was used. Two officers involved in the incident have been placed on administrative leave.

Kerry said in a statement that he regretted the incident.

"I believe I could have handled the situation without interruption, but again I do not know what warnings or other exchanges transpired between the young man and the police prior to his barging to the front of the line and their intervention," Kerry said.

"I was not aware that a taser was used until after I left the building," Kerry added. "I hope that neither the student nor any of the police were injured. I regret enormously that a good healthy discussion was interrupted."

Kerry said that it's the first time in his 37 years of public appearances that he's had a dialogue "end this way."

Kerry pointed out that he asked police to let him answer the question -- and he says he was "in the process of responding" when the student was taken away.
