Huntsman, a former Utah governor, said he would support the "party's nominee" and hopes he will grow throughout the campaign. 

"Certainly, I have concerns about some of the things he's said and his stylistic approach, but then I say OK, he has a unique opportunity to bring together constituents under the Republican banner that really have never joined before," he said during an interview with radio host John Catsimatidis. 

"The campaign is just ramping up, and he has a long way to go, and I believe the candidates grow and develop during the course of a yearlong campaign and voters are able to see them for what they are and then make an informed decision."

Huntsman himself ran for president in 2012, losing the Republican nomination to Mitt Romney.
