(CNN) New Jersey Gov. Chris Christie said there is "a lot of work to do" to ease tensions between police officers and the communities they serve.

"That's why I've advocated for body cameras for law enforcement," Christie told CNN's Jake Tapper in an interview that aired Wednesday morning.

Christie, a former U.S. attorney and potential GOP presidential contender, said body cameras would benefit both police officers and the public.

"I think law enforcement should want to have what they do recorded for their own safety and protection and for the safety and protection of those they served," he said.

Christie also pointed to Camden, New Jersey as "a great example of what can be done across the country."
