The U.S. Chamber of Commerce stepped into the California governor's race on Monday as it began airing an attack ad against Democratic gubernatorial candidate Jerry Brown.
The business group's TV ad, which is airing in Los Angeles, echoes one of Republican Meg Whitman's key campaign themes -- recent job losses in California.
It cites a comment that Brown, the state's attorney general, made in 2008, when he said he had 1,100 attorneys at the Department of Justice waiting to file lawsuits.
"I don't do much these days except sue people," Brown said.
Brown's campaign said the self-deprecating comment was made as part of a discussion about the administration of President George W. Bush refusing to accept state laws on auto emissions standards, which Brown says forced him to repeatedly file lawsuits.
The chamber's ad also says California has one of the worst legal climates in the country, which is sending jobs and business out of the state.
Brown's campaign noted that the study the claim is based upon was sponsored by the U.S. Chamber of Commerce.
The chamber last week released an attack ad against Democratic Sen. Barbara Boxer, who faces Republican Carly Fiorina in November.
