LARAMIE, Wyo. (AP) — University of Wyoming police are investigating after someone covered the American flag on campus with a rainbow flag commonly associated with gay pride.

On Monday, the first day of UW's spring semester, someone zip tied the American flag on campus so it couldn't unravel and put a pride flag in its place.

Director of Institutional Communication Chad Baldwin says UW accepts people with differing opinions, but moving the American flag is not a preferred method of protest.
