A state committee declined, on a party-line vote Monday, to investigate whether former Gov. John Hickenlooper misused a federal fund to pay for his defense of possible ethics violations. Republicans Sen. Paul Lundeen of Monument and Rep. Rod Bockenfeld of Watkins brought forward a request for the Legislative Audit Committee to conduct the review. In a letter to the committee, they asked for the investigation “into the inappropriate, perhaps illegal, use of federal funds for the purpose of paying legal bills for former Governor John Hickenlooper.” A Denver lawyer has received $43,390 so far to defend Hickenlooper in the Colorado Independent Ethics Commission’s investigation into his acceptance of private flights.
