NEW YORK - The last of four defendants charged in the prostitution scandal that brought down former Gov. Eliot Spitzer pleaded guilty Monday to arranging trysts between high-priced escorts and clients.

Tanya Robin Hollander, of Rhinebeck, N.Y., admitted she conspired to violate the travel act, which prohibits crossing state lines to further an illegal business.

Hollander, who worked as a booker for the Emperors Club VIP, told the court she began looking for work early last year to supplement her job as a holistic health counselor.

She said she began working for the service in June 2007, arranging dates between hookers and customers at various locations in the United States and Europe.

U.S. District Court Judge Deborah A. Batts asked Hollander if she knew what she was doing was against the law.

“It became apparent,” Hollander said.

With the plea, Hollander became the last of four club employees arrested in March to admit a role in the illicit business. Prosecutors haven't revealed whether Spitzer will be charged in the probe, which began last summer after a series of suspicious banking transactions.

Spitzer resigned March 12 after he was identified as Client-9, whose meeting with a prostitute known as Kristen in a Washington, D.C., hotel the night before Valentine's Day was outlined in an affidavit filed in connection with the case.

In June, Emperors Club VIP operator Mark Brener, 62, of Cliffside Park, N.J., pleaded guilty to conspiracy to commit a prostitution offense and conspiracy to commit money laundering. That month Brener's former girlfriend, Cecil Suwal, 23, pleaded guilty to money laundering, conspiracy and conspiring to promote prostitution, admitting her role as a manager of the company.

In May, Temeka Lewis, a booking agent for the escort service, pleaded guilty to promoting prostitution and money laundering.

All three are awaiting sentencing.

Hollander does not have a cooperating agreement with the U.S. attorney's office. Her lawyer, Michael Farkas, said she tried to cooperate but the government wasn't interested.

Farkas called Hollander “a good and decent person” but a little “naive.” He said Hollander played a minor role in the scandal.

Farkas didn't have any information about the case against Spitzer or whether prosecutors intended to charge him. But he said if the former governor committed a crime, “he should be charged like anyone else.”

Farkas said Hollander, 36, could receive a maximum of five years in prison. However, sentencing guidelines call for six to 12 months. The guidelines also allow the option of probation, he said.

“We're seeking the absolute minimum possible - anything to avoid jail time,” Farkas said. “We think we have a very strong argument ... she's been honest and upfront since the beginning.”

Hollander is scheduled to be sentenced Nov. 25. She remains free on a personal recognizance bond. Brener faces between 2 and 2.5 years in prison when he's sentenced next month.

Under federal sentencing guidelines, Lewis could do 16 months in prison, and Suwal's plea bargain calls for her to get between 21 and 27 months in prison.

Spitzer has not commented on the possibility of charges against him. A spokeswoman for Spitzer declined to comment Monday.
