Sources tell NY1 the FBI is looking into the hiring practices of the governor's office.

Sources tell NY1 the probe was launched by the U.S. attorney’s office for the eastern district of New York. 

It relates to the Cuomo administration's practice of taking on additional staff and paying them through other state agencies.

People close to the administration say the practice has been happening in state government for decades.

Nevertheless, NY1 can confirm, based on sources, that the FBI is looking into this matter.

Both the FBI and the eastern district declined to comment.
