Former U.S. Senate candidate and retired Air Force Col. Rob Maness is throwing his support behind U.S. Rep. Bill Cassidy in his effort to unseat incumbent Sen. Mary Landrieu.

According to the Maness campaign, Cassidy, Maness, and their wives enjoyed dinner together at a New Orleans restaurant, where the two discussed Cassidy's Senate campaign.

Maness said the two talked about "important point of public policy including the ongoing situation in Bayou Corne, the REDEEM Act, and Sen. Lee's Conservative Reform Agenda."

Maness and Cassidy were involved in a sometimes contentious campaign to defeat Landrieu, who has been in the Senate for 18 years. Cassidy and Landrieu head to the Dec. 6 runoff after neither candidate garnered at least 50 percent of the vote.
