In June, the 8th U.S. Circuit Court of Appeals tossed out a $1.8 million verdict awarded to Ventura against Kyle, the author of "American Sniper." An appeals court recently denied Ventura's request for a rehearing.
Ventura, a former SEAL, took issue with Kyle's claim in his autobiography that he punched Ventura at a California bar in 2006 for making offensive comments about the SEALs. Kyle's autobiography was the basis for a 2014 film.
In an interview with the Star Tribune this week, Ventura said he and his attorney plan to take the case to the Supreme Court and face a second trial.
