The attorney who represented U.S. Sen. David Vitter’s gubernatorial campaign earlier this month is the same one who is representing Texas Brine, the company blamed for the Bayou Corne sinkhole disaster.

Why might that matter?

Vitter’s Super Pac launched a television ad on Saturday that attacks Republican rival Scott Angelle’s handling of the sinkhole as secretary of the Department of Natural Resources. Angelle is now a member of the state Public Service Commission.

Texas Brine, the company at the center of criticism about Bayou Corne, is represented by James Garner, a New Orleans attorney at Sher Garner Cahill Richter Klein & Hilbert. Texas Brine is the target of a class action lawsuit filed in Assumption Parish.

It was Garner who wrote television stations two weeks ago demanding that they pull an ad by the Louisiana Water Coalition that attacks Vitter for his 2007 prostitution scandal. The TV stations complied but the ad began airing the following day after it was tweaked.

Garner did not return a phone call seeking comment.
