Video Description: (http://www.davidrivkin.com) David Rivkin sat live with MSNBC's Countdown with Keith Olbermann, subbing for the evening was Larry O'Donnell. The number topic centered on former Vice President Dick Cheney's daughter, Liz Cheney, for her Keep America Safe ads last week. She accused Guantanamo Bay lawyers as "terrorists." Ken Starr was on the night before and had harsh words for Cheney. Now it was Rivkin's turn to rebuke Cheney for demonizing lawyers (original air date March 10, 2010).
