Retired NFL quarterback Brett Favre pitches his support for Mississippi Sen. Thad Cochran in a TV ad sponsored by the U.S. Chamber of Commerce.
It's the latest celebrity endorsement in a hard-fought and sometimes bizarre race in which a tea-party backed candidate, state Sen. Chris McDaniel, is trying to unseat the former Senate Appropriations chairman. The Republican primary runoff is Tuesday.
Former GOP presidential candidates Sarah Palin, Rick Santorum and Ron Paul have been to Mississippi for McDaniel, as have the parents from the reality show "19 Kids and Counting." Former game show host Chuck Woolery is to be part of a Tea Party Express tour for McDaniel, starting Friday.
Cochran's campaign says 2008 Republican presidential nominee Sen. John McCain will stump for Cochran Sunday on the Gulf Coast.
