 E-mails obtained by WTAE TV of Pittsburgh between City Bureaucrats, Councilmembers, the Penguins and the Mayor's office supported Peduto's claims.In February 2013 both the FBI and IRS subpoenaed boxes full of documents from police headquarters and the independently run police credit union concerning thousands of deposits and withdrawals of tax payer money from non-authorized accounts, though at least one account dates back to 2004, prior to Mayor Ravenstahl's tenure, and as yet no allegations have been made against Mayor Ravenstahl.On February 21, 2013, Mayor Ravenstahl admitted that members of his police protection unit also drew from the non-authorized credit union accounts under investigation by the FBI and IRS, though neither he nor the officers were aware those credit cards were tied to the accounts or were unauthorized by the city controller's office.
