A footnote from the Starr report:

1128. In claiming that this statement was true, the President was apparently relying on the same tense-based distinction he made during the Jones deposition. See Clinton 8/17/98 GJ at 59-61 ("It depends on what the meaning of the word 'is' is. If the—if he—if 'is' means is and never has been, that is not—that is one thing. If it means there is none, that was a completely true statement.... Now, if someone had asked me on that day, are you having any kind of sexual relations with Ms. Lewinsky, that is, asked me a question in the present tense, I would have said no. And it would have been completely true.")

...and from the president's videotaped testimony:

If the deponent is the person who has oral sex performed on him then the contact is not with anything on that list, but with the lips of another person.
