The special counsel’s office has expressed interest in issuing a subpoena to a woman who gained notoriety a decade ago for running a prostitution service in Manhattan, the woman, Kristin Davis, said in a brief phone interview Saturday morning.

Ms. Davis, 43, said she was unaware what information she might possess that would be of interest to the special counsel, Robert S. Mueller III, who is investigating Russian interference in the 2016 election.

“I don’t know at this time,” Ms. Davis said. But she confirmed that the special counsel’s office had “contacted us asking where they can serve” a subpoena.

In 2008, Ms. Davis, known in the tabloids as the Manhattan Madam, claimed to have supplied escorts to Eliot Spitzer, who resigned as governor of New York in 2008 after The New York Times reported that he had been ensnared by a federal investigation into prostitution. Mr. Spitzer denied any association with Ms. Davis, who spent several months at Rikers Island for running a prostitution ring.
