CONCORD, N.H. (AP) — Republican presidential contender Jon Huntsman isn't apologizing for taking a job in the Obama administration.

During a testy exchange Sunday morning, Huntsman tells Mitt Romney that he'll always put his country first regardless of who's in the White House.

Romney has criticized Huntsman for serving the Obama administration while Romney helped get Republicans elected back home. And he's going after Huntsman for praising Obama's past leadership.

The former Utah governor served as ambassador to China until resigning earlier in the year to launch his presidential campaign. He had previously served Republican presidents.

Romney says the best person to run against Obama isn't someone who worked for him.

And Huntsman answers that political attacks like Romney's are what's wrong with the country. He says America is tired of division.
