Rep. Richard Hanna (R-N.Y.) endorsed Jon Huntsman for president on Monday.

The endorsement is the first for Huntsman by a sitting member of Congress and came a day before the New Hampshire primary.

"I support Jon Huntsman because he stands for pro-growth economic solutions, individual liberty, and a strong, smart America on the world stage," Hanna said according to

Hanna, who is a Democratic target this year, said Huntsman called him roughly a month ago to ask for the New York congressman's support.

The endorsement is the continuation of a small string of backings the former Utah governor received in recent days. Huntsman was also endorsed by the Boston Globe editorial page and the Concord Monitor of New Hampshire.

Huntsman has bet his campaign's future on a good showing in New Hampshire — he's focused almost all of his campaign's resources there and held more than 150 town-hall events there. Recent polling has shown Huntsman's efforts are bearing some fruit.

On Monday, a Suffolk University Poll found Huntsman in third place with 13 percent support among New Hampshire voters, behind Mitt Romney at 33 percent and Ron Paul. For most of his time in the 2012 Republican presidential race, Huntsman has struggled to gain traction and get to the upper half of the Republican pack in the polls. The Suffolk poll is one of the latest to have found Huntsman with a modest increase in support among Granite State voters.
