The last of the four defendants implicated in the ring that supplied Eliot Spitzer with prostitutes pleads guilty in federal court, but federal prosecutors still won't say if they plan on charging the former governor with a crime.

Tanya Hollander, 36, whom authorities say acted as a booker for Emperors Club VIP, is charged with conspiracy to violate the Travel Act. The law states it's illegal to cross state lines while furthering an illegal business.

"Ms. Hollander was a minor player in this enterprise,” said Hollander’s attorney Michael Farkas. “She's been honest and upfront since the beginning and she wants nothing more than to put this behind her and get back to helping people."

Hollander said in court she's an holistic healer, but started working part-time at a company called QAT Consulting. She said at first she had no idea it was actually an illegal escort service called Emperor's Club VIP, but she admitted that she continued to book clients nationally and abroad once she figured it out.

Prosecutors say Hollander booked liaisons between prostitutes and clients of the high-class prostitution ring that brought down the former governor.

Hollander’s attorney says he doesn't think his client booked any trysts for Spitzer – named in court documents as the now-infamous "Client Number 9" – who booked a prostitute for the Mayflower Hotel in Washington the night before Valentine's Day.

He resigned in March after his name came up by chance during a federal investigation of the operation.

Hollander's attorney says his client offered to cooperate with federal prosecutors and they declined. The U.S. Attorney's Office has not said if it intends to charge Spitzer with any crime. Hollander's attorney says they should.

"I believe, at the very least, he is a potential co-conspirator,” said Farkas.

All four defendants in the case have now pleaded guilty to crimes in federal court and are awaiting sentencing.

Hollander faces up to five years in prison, but she could possibly get probation.
