Enter Brian's website from the front page (he has an ad for his "Best of Brian Whitman" with Sean Hannity on his front page), then click on "Audio Vault." There are 12-13 groups of sound clips, and you can go through all of them when you have time (Whitman does great imitations of people like John Kerry, Michael Jackson, Joe Lieberman, Al Gore, etc.). The best Teresa Heinz Kerry clip is Clip #4 in Group 1.
Great! Thanks AC.
