(CNN) - Former Massachusetts Gov. Mitt Romney will unveil a big endorsement Tuesday afternoon in New Hampshire, and his rival Rick Perry's campaign chalked it up to politics as usual.
"Northeast Republicans are sticking together in this case," Texas Gov. Rick Perry's Communications Director Ray Sullivan said in an interview on Fox News.
New Jersey Gov. Chris Christie will endorse Romney's candidacy for the 2012 GOP presidential nomination at an event in the first-in-the-nation primary state one week after he declined his own bid for the presidency for a final time. And perhaps Christie's returning a favor.
Romney endorsed Christie's New Jersey gubernatorial candidacy in 2009, when Christie was considered the moderate Republican in the race.
In a written statement, Sullivan said, "“Gov. Perry has the utmost respect for Gov. Christie and looks forward to his help unseating President Obama next year. Until then, Gov. Perry will continue traveling the country talking about job creation and getting America working again."
