Remember that was the one thing he was going to fix.
"Back in April 2014, Chris Abele was notified of an unresolved pension issue that was left over from the Scott Walker regime. The issue had been dormant since 2007 as the County was awaiting instructions from the IRS about how to resolve their accounting error. Upon this revelation, County Executive Abele directed a letter to be sent to the over 200 affected retirees informing them of imminent changes to their pensions. No further information was provided and retirees were informed that more information would be provided in September, five months later. Along with the letter, Chris Abele did an interview with the Milwaukee Journal Sentinel, which led to the April 23rd article entitled, "Milwaukee County Demands Pension Repayments Because of 'Buyback' Errors." For those retirees, that article added context to the cryptic letter they received that week. That context horrified the retirees because Abele was essentially threatening to send a debt collector to recoup pension money that had been spent decades ago."
