Chamber of Commerce funnels $100K to back Thad Cochran

The U.S. Chamber of Commerce has put $100,000 into the Mississippi GOP Senate race, backing up its pledge to help Sen. Thad Cochran defeat a tea party opponent in the June 3 primary election.

The powerful business lobby cut that big check to Mississippi Conservatives PAC on May 5, according to Federal Election Commission filings. Headed by Republican National Committee official Henry Barbour, the PAC has already spent nearly $700,000 helping Cochran in his race against state Sen. Chris McDaniel.
