New York Gov. Eliot Spitzer told senior members of his administration that he was involved in a prostitution ring, the New York Times reported Monday.
Spitzer is expected to make an announcement at 2:15 p.m.
The newspaper reported that the governor met with his senior aides earlier Monday afternoon after cancelling scheduled events for Monday.
Spitzer is expected to make an announcement Monday afternoon.
Spitzer, 48, is married and has three daughters.
Details about the prostitution ring were not immediately clear.
But last week, federal prosecutors in Manhattan filed conspiracy charges against four people accusing them of running a prostitution ring that charged wealthy clients in Europe and the U.S. thousands of dollars for prostitutes.
The Web site of the Emperors Club VIP displays photographs of the prostitutes' bodies, with their faces hidden, along with hourly rates depending on whether the prostitutes were rated with one diamond, the lowest ranking, or seven diamonds, the highest. The most highly ranked prostitutes cost $5,500 an hour, prosecutors said.
Spitzer has built his political legacy on rooting out corruption, including several headline-making battles with Wall Street while serving as attorney general. He stormed into the governor's office in 2006 with a historic share of the vote, vowing to continue his no-nonsense approach to fixing one of the nation's worst governments.
Time magazine had named him "Crusader of the Year" when he was attorney general and the tabloids proclaimed him "Eliot Ness."
But his stint as governor has been marred by several problems, including an unpopular plan to grant driver's licenses to illegal immigrants and a plot by his aides to smear Spitzer's main Republican nemesis.
Spitzer had been expected to testify to the state Public Integrity Commission he had created to answer for his role in the scandal, in which his aides are accused of misusing state police to compile travel records to embarrass Senate Republican leader Joseph Bruno.
Spitzer had served two terms as attorney general where he pursued criminal and civil cases and cracked down on misconduct and conflicts of interests on Wall Street and in corporate America. He had previously been a prosecutor in the Manhattan District Attorney's Office, handling organized crime and white-collar crime cases.
His cases as state attorney general included a few criminal prosecutions of prostitution rings and into tourism involving prostitutes.
In 2004, he was part of an investigation of an escort service in New York City that resulted in the arrest of 18 people on charges of promoting prostitution and related charges.
