The Senate Whitewater hearings drew to a close today with last-minute witness David Margolis, as associate deputy attorney general,flatly contradicting the testimony of former White House Counsel Bernard Nussbaum. According to Margolis, the White House and the Department of Justice agreed on the day after Vincent Foster's death on a plan for searching his office. Under the plan, Department of Justice lawyers with security clearances would briefly scan each document for highly-sensitive content, then turn over every other document to the Park Police. But when Margolis arrived for the search the next day, Nussbaum, he says, told him that the plan had changed. No documents would be given to the Park Police, nor would the Justice Department lawyers be allowed to read them.
