LAWRENCE, Kan. (AP) _ Racial tensions are growing at the University of Kansas with a call for three top Student Senate leaders to resign and a recent graduate initiating a hunger strike. The Senate's Student Executive Committee is demanding that Student Body President Jessie Pringle, Student Body Vice President Zach George and Chief of Staff Adam Moon step down by Wednesday. The committee took up the issue Friday, voting 6-3 that it had no confidence in the three leaders. One member abstained from the vote. The three embattled leaders released a statement Saturday, saying they plan to continue serving and professing support for minority groups.
