New Jersey Gov. Chris Christie has returned to New Hampshire as he struggles to press forward with a likely presidential bid following indictments in the George Washington Bridge scandal.

The governor attended a series of events and meet-and-greets Thursday that will extend into Friday.

The trip includes a visit to a drug treatment center in Manchester and a keynote speech at a Lincoln Day dinner. He'll also lead another happy hour-timed town hall event Friday evening at Fury's Publick House bar in Dover.

The trip marks Christie's first to New Hampshire since two former aides were indicted and another pleaded guilty to charges stemming from a scheme to shut down access lanes to the bridge. It allegedly was done to punish Fort Lee Mayor Mark Sokolich, who didn't endorse Christie's re-election in 2013.
