New Jersey Gov. Chris Christie will go on the stump in New Hampshire for Mitt Romney on Wednesday.

The Republican governor will be featured at two appearances for Romney, one at Romney's New Hampshire headquarters and the other at a house party in Nashua, according to Romney's campaign. Christie will then go to Boston to watch Romney participate in a Republican presidential debate, according to the Manchester, N.H., Union Leader.

Christie's New Hampshire appearances are the first public events he's done for Romney.

Christie endorsed Romney in October. Previously, Christie's name had repeatedly come up as a possible addition to the Republican presidential field, despite strong denials from the New Jersey governor that he had any interest in running for president.

In endorsing Romney, Christie stressed that he was more interested in his current job than joining the former Massachusetts governor on the presidential ticket should Romney get the nomination.

"That’s going to be Gov. Romney’s choice," Christie said in October. "I’ve told him my only interest is helping him get elected and serving my state."

Christie said he expected to continue to be New Jersey's governor through 2013.

"I have every expectation of serving my term through 2013," he said at the time.
