JACKSON, Miss.—Mississippi's senior U.S. senator, Thad Cochran, is endorsing fellow Republican Mitt Romney for president, as he did in 2008.
The Romney campaign announced Cochran's support in a news release Wednesday.
Cochran is the highest-ranking Republican on the Senate Appropriations Committee. He was first elected to the Senate in 1978, after having served six years in the U.S. House.
Cochran says in the Romney news release that the U.S. "cannot afford another four years" of President Barack Obama's policies and that Romney, a former Massachusetts governor, "has the pro-growth message and the unmatched experience that will be required to improve our economy."
Another prominent Mississippi Republican, Gov. Haley Barbour, says he doesn't intend to endorse a presidential candidate until the GOP chooses its nominee.
