Luther Strange and Roy Moore are exchanging jabs following a cancelled debate ahead of the GOP runoff for Jeff Sessions U.S. Senate seat. The two contenders have tentatively agreed to face off on stage later this month. The two traded accusations after Moore withdrew from a debate hosted by the Alabama Policy Institute, a conservative think tank. Moore claims he withdrew because API's president also serves as treasurer of the PAC backing Strange. The Strange campaign then accused Moore of ducking a debate. Moore then challenged Strange to meet him in a "Lincoln-Douglas style" debate to present issues without a moderator or questions from the news media. The two may attend a debate hosted by Raycom news media next Friday. The winner of the GOP runoff will face Democrat Doug Jones in December. Jones was a U.S. Attorney who prosecuted members of the KKK involved in the 16th Street Baptist Church bombing. He’s been endorsed by former Vice President Joe Biden, and civil rights icon and Congressman John Lewis.
