Often she said she could not remember details of events.

At one point in her appearance on 27 January prosecutors repeatedly pressed her to confirm that Ms Lewinsky had told her: "As long as no one saw us - and no-one did - then nothing happened."

Without answering, Mrs Currie asked if she could step outside for a moment and the jury's foreperson told her: "You are reminded you are under oath."

When Mrs Currie returned, she said: "My memory is a little better - but not much."

She continued, "If that was said, I would have said: 'Stop, stop I don't want to hear anymore'".

As the questioning continued, Mrs Currie said flatly: "I believe Ms Lewinsky said that."

Mrs Currie said Clinton's interest in Lewinsky was different than with other interns, saying Lewinsky had a "crush" on the president.

She also said the two were alone in the White House several times for 20 to 30 minutes, contrary to what Mr Clinton swore in his deposition in the Jones case.
