DES MOINES — Democratic leaders of the Iowa House and Iowa Senate on Monday called on Republican Gov. Kim Reynolds to expand the independent investigation of David Jamison and the Iowa Finance Authority.“The fallout from the firing of David Jamison should be a wake-up call to you,” said Senate Democratic Leader Janet Petersen of Des Moines, who signed the letter along with House Democratic Leader Mark Smith of Marshalltown.“David Jamison’s disgusting behavior and the failure of key staffers in your administration to address the problem over a period of years highlight the alarming fact that executive branch employees are afraid to report illegal and highly inappropriate behavior,” added Petersen.Monday’s call follows Reynolds last Friday that she has ordered an independent review of the IFA work environment that led to the March 24 firing of executive directorJamison over sexual harassment allegations.That dismissal came after two years of what one employee called “disgusting and abhorrent behavior” that had gone unreported by IFA staff due to retaliation fears.The governor has asked Des Moines lawyer Mark Weinhardt to head an investigation and report his findings back to her staff and the Iowa Attorney General’s Office.Weinhardt was directed to look into the conduct that led to Jamison’s firing and any similar incidents or conduct during his tenure as executive director.
