DES MOINES, Iowa (AP) — A state senator from Des Moines has asked Gov. Terry Branstad to turn over public documents related to settlements reached with employees who were laid off then paid to sign agreements to keep it quiet. Sen. Janet Petersen, a Des Moines Democrat, and chairwoman of the Iowa Senate Oversight Committee, says she wants copies of any such agreements since January 2011. She also wants to know who requested the agreements and who authorized the payments.

On Sunday the Des Moines Register reported that more than $280,000 was paid to six former state employees. Lt. Gov. Kim Reynolds says she and Branstad were unaware of the agreements and a comprehensive review is under way. Branstad spokesman Jimmy Centers says results of the review and any action taken will be made public.
