Clinton had also said, "There is not a sexual relationship, an improper sexual relationship or any other kind of improper relationship" which he defended as truthful on August 17, 1998 because of his use of the present tense, arguing "it depends on what the meaning of the word 'is' is". Starr obtained a blue dress from Lewinsky with Clinton's semen stained on it, as well as testimony from her that the President had inserted a cigar into her vagina. Clinton stated, "I did have a relationship with Miss Lewinsky that was not appropriate", but he denied committing perjury because, according to Clinton, the legal definition of oral sex was not encompassed by "sex" "per se". In addition, he relied on the definition of "sexual relations" as proposed by the prosecution and agreed by the defense and by Judge Susan Webber Wright, who was hearing the Paula Jones case. Clinton claimed that certain acts were performed "on" him, not "by" him, and therefore he did not engage in sexual relations. Lewinsky's testimony to the Starr Commission, however, contradicted Clinton's claim of being totally passive in their encounters.
