SALT LAKE CITY (AP) — Four Republican governors are signing a pledge to oppose any increase in the federal debt without spending cuts and a balanced budget amendment.

Utah Gov. Gary Herbert announced Thursday that he is joining Texas Gov. Rick Perry, South Carolina Gov. Nikki Haley and Alaska Gov. Sean Parnell in the pledge.

Herbert says in a news release that he signed the Cut, Cap and Balance pledge to encourage the federal government to control spending.

Eight of the candidates competing for the Republican presidential nomination have also signed the pledge. Only former Utah Gov. Jon Huntsman has refused to sign it.

The pledge has also been signed by 12 U.S. senators and 29 U.S. representatives.
