Former Vikings punter Chris Kluwe has retained Twin Cities attorney Clayton Halunen to represent him in the team's investigation into alleged homophobic comments by an assistant coach.

According to a press release, Halunen will serve as co-counsel with the National Center for Lesbian Rights.

The Vikings announced last week that they initiated an investigation to look into Kluwe's allegations that special teams coordinator Mike Priefer made repeated derogatory gay comments in 2012.

The team announced that former Chief Justice of the Minnesota Supreme Court Eric Magnuson and former U.S. Department of Justice Trial Attorney Chris Madel will lead the investigation.
