It looks innocuous enough — a long-sleeved, blue Gap shirtdress with a self-fabric belt — but intern Monica Lewinsky’s stained frock became the key piece of evidence in the Starr investigation and impeachment proceedings of Bill Clinton. With its traces of presidential DNA, the dress proved indisputably that he did in fact “have sexual relations with that woman, Miss Lewinsky.”
Lewinsky received transactional immunity in exchange for grand jury testimony concerning her relationship with Clinton. She also turned over the semen-stained blue dress (that Linda Tripp had encouraged her to save without dry cleaning) to the Starr investigators, thereby providing unambiguous DNA evidence that could prove the relationship despite Clinton's official denials.
Pennsylvania artist Nelson Shanks told The Philadelphia Daily News that he painted in the shadow of a blue dress in the 2006 portrait -- a reminder of the political sex scandal between Clinton and former White House intern Monica Lewinsky.
Lewinsky scandal, 1998, January: Defense Dept. worker Linda Tripp delivers audiotapes revealing a sexual relationship between President Bill Clinton and a 22-year-old White House Intern, Monica Lewinsky. The news of this extramarital affair and the resulting investigation eventually leads to the impeachment of President Clinton in 1998 by the US House of Representatives and his subsequent acquittal on all impeachment charges of perjury and obstruction of justice in a 21-day Senate trial.
