New Jersey Governor Chris Christie's approval ratings have fallen after the one-time presidential hopeful endorsed Republican front-runner Donald Trump, according to a statewide opinion poll.

The poll by Fairleigh Dickinson University, released on Wednesday, showed that Christie's approval rating fell to 27 percent from 33 percent before the endorsement.

The drop was greater among those without party affiliation, with approval falling to 18 percent from 34 percent.
