Hillary at White House on 'Stained Blue Dress' Day Schedules show Hillary may have been in W.H. when the fateful act was committed.

March 19, 2008 -- Hillary Clinton spent the night in the White House on the day her husband had oral sex with Monica Lewinsky, and may have actually been in the White House when it happened, according to records of her schedule released today by the National Archives.

An initial review by ABC News of the 17,481 pages of Sen. Hillary Clinton's schedule as first lady, released today by the National Archives, also finds significant gaps in time and many days containing only "private meetings" at the White House with unnamed individuals.

The public schedule for Sen. Clinton on Feb. 28, 1997, the day on which Lewinsky's infamous blue dress would become stained by the president, shows the first lady spent the morning and the night in the White House.

The Feb. 28 schedule lists her as attending four "drop-by" events, closed to the press, between 11 a.m. and 12:30 p.m. and then records her as staying in the White House overnight that fateful day.

The schedule lists three different events occurring that evening at Washington theaters and the Kennedy Center but does not indicate if she attended.

According to the Starr report, President Clinton took Lewinsky into an Oval Office bathroom in the early evening, after recording a radio address. Forensic tests later "conclusively" showed that the blue dress she was wearing "was stained with the President's semen," according to the Starr report.

In December 2000, when both of Hillary Clinton's brothers were involved in trying to broker pardon arrangements for associates, several days of documents show only a long list of "private meetings" at the White House.

Between Dec. 1 and 22, Clinton had a total of 25 "private meetings" before the day on which a first round of pardons was announced by her husband.

The records do show Sen. Clinton twice meeting with Denise Rich at charity events in October and November 2000, at a time when Rich was seeking a pardon for her billionaire ex-husband, Marc Rich, who had fled the U.S. on tax charges. Clinton pardoned Rich in the last hours of his administration in January 2001.
