Top Presidential aides forced to testify
Aides evidence could be most "relevant and important" in the case
A federal judge in the United States has ordered two senior advisers to President Clinton to give evidence into allegations against him of sexual misconduct with a former White House worker, and of a conspiracy to cover it up.
Mr Clinton's lawyers had argued that the two men, Bruce Lindsey and Sidney Blumenthal, were covered by executive privilege and so should not have to testify in the case involving Monica Lewinsky.
However, the judge ruled that the importance of their evidence to the investigation meant they would have to do so.
President Clinton and Monica Lewinsky have both denied under oath that they ever had a sexual relationship.
The special prosecutor's team has spent months trying to prove that they had, and that they lied to lawyers who were investigating charges of sexual harassment against the president.
Mr Starr's request for voice, handwriting and fingerprint samples could be in preparation for summoning Ms Lewinsky to give evidence in secret court hearings.
The ruling ordering President Clinton's advisers to give evidence came on the same day that an open letter by Ms Lewinsky's lawyer, William Ginsburg, was revealed in a legal journal.
In it, Mr Ginsburg called for Kenneth Starr to be fired and he said that, at best, his case involved a consensual sexual relationship between his client and President Clinton.
The lawyer immediately tried to clarify his remarks, saying the reference was "not saying anything about Monica."
