Investigators are focusing on possible violations of securities law by Gov. Chris Christie’s administration involving money allocated to bridge repairs. The New York Times reported Tuesday that the Manhattan district attorney and the Securities and Exchange Commission are investigating Christie’s office for lobbying the Port Authority to divert $1.8 billion away from a canceled rail-tunnel project and toward repairing the Pulaski Skyway bridge. The Pulaski is a state bridge, outside of the Port Authority’s purview. The Christie administration recast the bridge as an access road to the Lincoln Tunnel (they’re not connected) in order to justify using Port Authority funds.
