LAWRENCE, Kan. (AP) — The University of Kansas student government has taken steps to impeach three top leaders after concerns were raised about their handling of racial issues.

The Lawrence Journal-World reports that the Student Senate introduced a bill of impeachment Wednesday night against Student Body President Jessie Pringle, Student Body Vice President Zach George and Chief of Staff Adam Moon. The process could take weeks.

The three leaders said Wednesday that they wanted to remain in the Student Senate. On Monday, they issued a joint statement outlining 11 proposals for increasing diversity within student government.

A student government committee is pushing for their departure, based in part on what members see as an inadequate response to diversity demands to the university from a campus protest group called Rock Chalk Invisible Hawk.
