A county prosecutor says he expects to interview Kansas Gov. Sam Brownback about meetings he had at his official residence with state legislators.

Shawnee County District Attorney Chad Taylor described Brownback as a witness in his investigation of whether the gatherings violated the state’s open meetings act.

Taylor spoke Friday after warning Brownback and state lawmakers to preserve records and electronic files that could be evidence. He said at a news conference he will release legislators from that requirement as he sorts through who went to the meetings and who did not.

Brownback has said he’ll cooperate fully, but Taylor acknowledged he had not discussed an interview with the governor’s staff.
