Kluwe alleged in a Deadspin story that he was released before the season as a result of being outspoken in support of same-sex marriage and was a victim of homophobic remarks by Vikings special teams coordinator Mike Priefer during the 2012 season.
"I cooperated fully for the investigation,'" Kluwe told the Pioneer Press about Friday's meeting. "The investigation is ongoing. I'm not going to comment on anything else. But I was asked questions, and I answered them. ... I can say it was a productive meeting."
Kluwe also alleged in the Deadspin story that Vikings general manager Rick Spielman and former coach Leslie Frazier both asked him to keep quiet about his views on social issues, most notably his support for same-sex marriage.
According to Kluwe's piece, which was titled "I was an NFL player until I was fired by two cowards and a bigot," Priefer allegedly said in a team meeting that "we should round up all the gays, send them to an island and nuke it until it glows."
Priefer responded with a strongly worded statement, saying, "I vehemently deny today's allegations made by Chris Kluwe." The Vikings reiterated in a statement that Kluwe was released after the 2012 season strictly because of his football performance, not because of his views.
According to the Pioneer Press, Kluwe provided names of witnesses during his meeting at the Minneapolis law offices of Eric Magnuson and Chris Madel, who have been commissioned by the Vikings to investigate the allegations.
"We interviewed him for approximately five hours,'' Madel told the newspaper. "He answered all of our questions. There were no agreements with respect to anonymity of any witnesses or any other facts.''
