MEQUON, Wis. (AP) — Gov. Scott Walker will be giving his first commencement address when he addresses graduate students at Concordia University in Mequon. Walker will address nearly 500 graduate students Friday, at the school north of Milwaukee. The ceremony begins at 6 p.m. Walker’s office says the governor had been invited to give other commencement speeches but this is the first one that worked out. Walker went to Marquette University, although he left in 1990 when he was 34 credits shy of graduating. He has said he planned to go back and finish but his options were limited after he got married in 1993 and had a son in 1994. He recently said he’d like to complete his degree through the University of Wisconsin System’s new flexible-option degree program.
