Probe that snared Spitzer did not need OK from top

WASHINGTON/NEW YORK (Reuters) - The Republican U.S. attorney general was not asked to sign off on a politically explosive prostitution probe that could place New York's Democratic Gov. Eliot Spitzer in legal jeopardy.

Spitzer, identified by The New York Times as Client 9 in a federal complaint in the prostitution case announced last week, issued an unspecific apology on Monday and is facing widespread pressure to resign.

Experts said Spitzer could conceivably face criminal charges or be asked to testify in any trial involving the Emperors Club suspected prostitution ring. But so far he has not been charged with a crime and federal prosecutions are rare in circumstances such as those reported in the Spitzer case.

A federal official said Justice Department headquarters in Washington had been aware of the prostitution probe, but the U.S. attorney's office in the Southern District of New York, which led the investigation, had not requested approval to go forward.

"The United States attorney was not required to seek, and did not seek, approval of the attorney general or the deputy attorney general with respect to any investigative steps taken in this matter," the official said.

It is common in politically sensitive cases to alert top Justice Department officials, said King & Spalding lawyer Andrew Hruska, a former senior counsel to the deputy attorney general. In that position, "I would expect to get a pretty full briefing on the scope of the case," he said.

Some experts said it would be up to prosecutors to decide whether Spitzer, a former New York state chief prosecutor known as an anti-corruption crusader, could escape any prosecution by resigning.

The prostitution probe was launched in October 2007, when the department was under interim leadership following the resignation of Attorney General Alberto Gonzales. The current attorney general, former New York federal judge Michael Mukasey, was sworn in in November.
