A Wisconsin state senator is asking legislative leaders to file a suit against the University of Wisconsin System. Republican Steve Nass of Whitewater wants it to be determined if system leaders have to get legislative approval to enact COVID-19 restrictions. Nass sent a letter asking for the lawsuit to Senate Majority Leader Devin LeMahieu and Assembly Speaker Robin Vos Tuesday. U-W System President Tommy Thompson has rejected the idea that lawmakers must approve the restrictions before they can go into effect. There has been no indication from LeMahieu or Vos whether they might file the suit.
