Mississippi Gov. Haley Barbour said Tuesday from Iraq that he’s proud of the job American troops are doing.

Barbour and the governors of Georgia, Oregon and Wyoming are on a trip sponsored by the Department of Defense.

The trip was announced only after the governors arrived Tuesday. They were briefly in Kuwait before visiting U.S. troops in Iraq, including some from the Mississippi National Guard’s 155th Brigade Combat Team.

More than 3,000 members of the 155th are deployed in Iraq, and it’s the second tour of duty for many in the unit.

Barbour told reporters during a conference call that he can’t reveal where else the governors will go or when they’ll return. In 2005, Barbour and other governors traveled to Kuwait, Iraq, Afghanistan and Pakistan.
