Jesse Ventura was the one who filed a defamation suit against Cris Kyle about a chapter in his book "American Sniper," where Chris claimed he punched Ventura out in a bar in 2006, after Ventura made negative remarks about SEALS. Chris was killed in June 2013, but before the incident that took his life, he swore an affidavit to the court that what he wrote in the book was the truth. Ventura's suit proceeded against Kyle's estate. In 2014, a jury awarded Ventura $500,000 for defamation and $1.3 million for unjust enrichment. Kyle's widow appealed the decision, and in June 2016, a Federal Court of Appeals vacated the $1.8 million award. Ventura tried to appeal that decision to the Supreme Court, but they declined the case.
Ventura also sued Harper-Collins who had published the book, and settled out of court with them. Once he got the money from the settlement, he withdrew his suits against the book publisher, and the Kyle estate. I think the guy is a POS to go after the estate of a man and his widow. He's as bad as the Sandy Hook parents going after Alex Jones.
