The chairman of the Port Authority of New York and New Jersey is being investigated for possible conflicts of interest, sources tell NBC 4 New York.
Law enforcement officials confirm David Samson, a lawyer and ally of Gov. Chris Christie, is being investigated by the U.S. attorney's office in Manhattan and the FBI.
His name emerged in the news in January, when The Bergen Record reported that as Port Authority chairman he backed a plan to renovate a train station located closed to a planned housing complex proposed by a builder represented by his law firm.
The Port Authority had no immediate comment.
Samson was also recently pulled into the scandal engulfing Christie's administration over traffic jams near the George Washington Bridge.
His name surfaced in an email during the lane closures, when a Christie ally at the Port Authority emailed a then-Christie aide, noting that the jams had been cleared up.
"We are appropriately going nuts. Samson helping us to retaliate," the email said.
Samson has denied any involvement in the scheme.
