On July 28, 1998, a substantial delay after the public break of the scandal, Lewinsky received transactional immunity in exchange for grand jury testimony concerning her relationship with Clinton.[26] She also turned over a 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.[27]
Clinton admitted in taped grand jury testimony on August 17, 1998, that he had engaged in an "improper physical relationship" with Lewinsky. That evening he gave a nationally televised statement admitting that his relationship with Lewinsky was "not appropriate".[28][29]
