and i would -- i really would hope not. and i was -- i was heartened to see so many of our colleagues make it very clear they weren't involved in this in any way. >> mr. president, i asked you earlier if anyone on your staff wrote this op-ed. have you asked your staff? >> well, i thought you were speaking about the administration staff. let me be very clear. i'm 100% confident that no one on the vice president's staff was involved in this anonymous editorial. >> should all top officials take a lie detector test and would you agree to take one? >> i would agree to take it in a heartbeat. >> what do you make of all that, mark preston? it's just strange to hear, you know, what doesn't sound like a very adamant no, you know, we didn't have anything to do with this, and then all of a sudden say, well, i'll take a lie detector test. >> well, when is the last time you heard a vice president say i'll take a lie detector test to prove to the president that i have been loyal to him?
