It's a stupid use of legislative power as well as a dumb move politcally, but Nichols seems to be making an overreach as well tbh. Stating that a state agency cannot allow a specific group use state property or that state employees cannot work with said group as part of their official duties is a lot of things. Most of them stupid, but it isn't a removal of any civil rights. We don't have a civil right to use universtiy property in exchange for offering students internships. The School of Journalism created a special relationship with the WCIJ and the legislature made a petty and moronic decision in the middle of the night to forbid that relationship.
Not saying there aren't other constitutional (other legal) rights that might be getting streatched a bit here, but Nichols' theory is a pretty big reach.
