Lewinsky, 24, spent about three hours at the FBI's field office submitting handwriting and voice samples as well as fingerprints in compliance with a federal probe.

Neither Lewinsky nor her attorney William Ginsburg spoke to some 30 waiting reporters as they ducked into a car and left, escorted by federal agents in two other cars.

Lewinsky's evidence was given to representatives of special prosecutor Kenneth Starr. He is looking into allegations that Clinton had an affair with her, lied about it and asked her to lie.

"My daughter was a pawn and Kenneth Starr is trying to use her as pawn to get to the presidency," said her father, Bernard Lewinsky, a California oncologist. "This is unfair and it is totally un-American."

The former intern and the President allegedly had an18-month relationship. Lewinsky and Clinton have denied under oath having had any sexual relationship.

She is yet to testify before a federal grand jury about the matter, but her spokeswoman said she wants to tell her side of the story. Stripped of immunity from prosecution, she could be charged with perjury because of a previous sworn statement she made denying the relationship.

In their quest for evidence against Clinton, prosecutors are sifting through more than 20 hours of conversations between Lewinsky and former co-worker Linda Tripp, who secretly taped their discussions.

On the tapes, which Tripp turned over to Starr, Lewinsky reportedly describes her liaison with Clinton and explains how he and his close ally, attorney Vernon Jordan, urged her to lie to authorities to cover it up.

Jordan made his fourth appearance before the grand jury in Washington on Thursday. Jordan helped Lewinsky find a job and a lawyer when the scandal broke nearly five months ago. He said he will make a return visit inJune.

"For the fourth time, I have answered every question over and over again," an obviously exasperated Jordan told reporters on the courthouse steps.

Vernon's appearance came a day after a federal judge ordered two top White House aides to testify in the investigation, explaining the prosecutor's interests outweighed Clinton's claim of executive privilege.
