TOPEKA, Kan. (AP) — A top Kansas lawmaker is questioning an arrangement that has seen a state agency’s interim leader in the position for more than six months.

The Topeka Capital-Journal reports that Tim Keck has served as interim secretary for the Kansas Department for Aging and Disability since Jan. 1.

Democratic state Senate Minority Leader Anthony Hensley says a state law appears to prohibit acting secretaries from serving more than six months.

Gov. Sam Brownback’s office said the six-month limit doesn’t apply in this case because Keck in an “interim” secretary, not an “acting” secretary.

Keck began serving as the interim secretary before the legislative session and hasn’t been confirmed by the Senate. He also hasn’t been nominated by Brownback.

Keck took over as secretary after Kari Bruffett resigned to become the Kansas Health Institute’s policy director.
