The Vikings have retained a former chief justice of the Minnesota Supreme Court and a former federal trial attorney to conduct an investigation into Kluwe's allegations that he was released from the team due to his support of gay marriage. The team made the announcement on Friday, , Jan. 3, 2014, one day after Kluwe penned a scathing article alleging that special teams coordinator Mike Priefer made anti-gay comments during team meetings.
