New Jersey Gov. Chris Christie got into a heated exchange over pensions with a public school teacher at his latest town hall meeting.

The event Tuesday in Kenilworth also was interrupted several times by protesters angry over Christie's positions on immigration and other issues.

The teacher had accused Christie of favoring the rich and questioned the size of a settlement the state reached with Exxon Mobil Corp. over environmental damage. At one point, she told the potential Republican presidential contender: "I'm not here to be bullied."

The protesters were escorted out of the event by security as a largely friendly crowd cheered.

Christie has been holding weekly town hall meetings across the state to tout his proposal to further reform the state's public worker health care and pension system.
