(CNN) The New York State Department of Financial Services has opened an inquiry into the Trump Organization's insurance practices, sending a subpoena Monday to the company's longtime insurance broker, according to a person familiar with the matter.
The nine-page subpoena, sent to Aon Plc, was issued days after President Donald Trump's former personal attorney Michael Cohen suggested in testimony to Congress that the Trump Organization had inflated the value of its assets, this person said.
A spokeswoman for Aon on Tuesday confirmed receipt of the subpoena.
"We can confirm that we received a subpoena from the New York State Department of Financial Services and, as is our policy, we intend to cooperate with all regulatory bodies," the spokeswoman, Donna Mirandola, said in a statement. "We do not comment on specific client matters."
A lawyer for the Trump Organization declined to comment to CNN.
The subpoena was first reported by The New York Times.
The inquiry by the Department of Financial Services adds to a growing collection of investigations concerning Trump's family business, including an ongoing criminal probe out of the Manhattan US attorney's office and a broad document request on Monday by the House Judiciary Committee, which is seeking records from the company and several of its executives.
While the Department of Financial Services doesn't have the ability to bring criminal charges, it can refer its findings to state prosecutors for further action.
The department regulates financial institutions and insurers, and it can impose significant fines or other penalties if it finds impropriety.
During his testimony last week to the House Oversight Committee, Cohen told lawmakers that Trump had provided inflated assets to an insurance company. Asked who knew Trump had done so, Cohen named three Trump Organization executives: Allen Weisselberg, Ron Lieberman and Matthew Calamari.
Cohen also suggested in his testimony that the Trump Organization had provided financial statements that showed inflated assets to insurance companies.
"We would provide them with these copies so that they would understand that the premium, which is based sometimes upon the individual's capabilities to pay, would be reduced," Cohen said.
