"After Hurricane Katrina, Senator Cochran fought for us, pushing emergency relief funding through Congress," says the narrator of the 30-second TV ad. "But when trial lawyer Chris McDaniel was asked how he would have voted for Katrina, his response was, 'I don't know.'"
The minute-long companion radio spot criticizes McDaniel for the same remark.
In a recent interview with Politico, McDaniel declined to say definitively whether he would have voted for the 2005 relief bill. A McDaniel spokesman later told the publication that McDaniel would have voted yes.
The new ads come amid an escalating air war. The anti-tax Club for Growth, which is backing McDaniel, released an ad last week hitting Cochran for voting to raise the debt ceiling.
Cochran faces a potentially tough challenge from McDaniel. The senator got a new political headache this week when he received a low rating on the American Conservative Union's annual scorecard.
A McDaniel spokesperson didn't immediately respond to a request for comment on the new ads.
Meanwhile, the race took a new twist as Rep. Travis Childers (D) reportedly said he would run.
