Trustees at Wyckoff Heights Medical Center asked to consider a whopping $875,000 severance payout for its former CEO are balking at the package, sources told the Daily News. Some board members of the debt-burdened Bushwick hospital, which a state advisory panel has targeted for a three-way merger, have opposed paying 15 months of salary for former CEO Rajiv Garg. The hospital would also cover Garg's legal fees in an investigation of him and other former hospital higher-ups by the Brooklyn District Attorney.
