DES MOINES, Iowa (AP) — Settlement agreements are likely to continue to dominate the agenda at the Iowa Capitol this week as some lawmakers remain unsatisfied with discrepancies in testimony and answers they received during hearings last week.

Former employees testified at a Government Oversight Committee hearing Wednesday they were treated badly when fired in 2011 and were offered money to keep quiet about their dismissals. Department of Administrative Services Director Mike Carroll denied those allegations on Thursday in testimony to the committee that completely contradicted the workers.

Democratic Sen. Janet Petersen, chair of the Senate Government Oversight Committee, says she plans to ask state department heads and human resources officials to come before the committee. She’s waiting for the Department of Administrative Services to provide numerous documents about state contracts and hiring practices.
