MARGARET WARNER: First Lady Hillary Clinton has been subpoenaed by Whitewater Independent Counsel Kenneth Starr to appear before a federal grand jury here in Washington this Friday. For more on this unprecedented event we hear from Stuart Taylor, correspondent for the American Lawyer and Legal Times and a regular on the NewsHour. All first, first give us the context for this. Which grand jury exactly is it that the First Lady’s been asked to appear before?

STUART TAYLOR, The American Lawyer: The grand jury in Washington. There’s also a grand jury in Little Rock being run by the same Independent Counsel, Kenneth Starr, investigating Whitewater and related matters. And the two grand juries are dividing their work up roughly with the Washington grand jury investigating the things that happened in Washington since President Clinton took office, the Arkansas grand jury investigating things that happened in Arkansas earlier, but there’s great overlap between the investigations. And they share information with each other.

MARGARET WARNER: All right. And what do we know from the subpoena or from what’s come out about what she’s going to be asked to testify about?

MR. TAYLOR: Well, the subpoena and the fact that about six or seven other people were subpoenaed seems to indicate that the Independent Counsel is particularly interested in how these Rose Law Firm billing records for Hillary Clinton appeared mysteriously in the White House living quarters some two years after they had been subpoenaed and whether someone was hiding them or obstructing justice. However, the White House statement that was put out yesterday also indicated that the First Lady was prepared to discuss the content of the billing records which suggest that some of the questions may get into looking at particular entries and how do you explain this and how do you reconcile it with your testimony on that and so forth.
