ANDREW YOUNG, A ONE-TIME TRUSTED AIDE TO SENATOR JOHN EDWARDS, SPEAKS EXCLUSIVELY TO ABC NEWS' BOB WOODRUFF IN A SPECIAL EDITION OF "20/20" ENTITLED "THE SECRET," FRIDAY, JANUARY 29 AT 10PM/ET ON ABC

More of the Interview to Air on "Nightline"

Young's First Live Interview with George Stephanopoulos on "Good Morning America," Airing on Feb. 1

Andrew Young, a former longtime aide and trusted friend of Senator John Edwards, sat down for an exclusive interview with ABC News correspondent Bob Woodruff regarding his upcoming memoir, The Politician: An Insider Account of John Edwards's Pursuit of the Presidency and the Scandal that Brought Him Down. In his interview with Woodruff, Young chronicles his time with Senator Edwards, including his efforts to hide the secret that would eventually shock the American public, FRIDAY, JANUARY 29 on ABC News' "20/20" (10:00-11:00 p.m., ET).

Amidst swirling rumors that the Senator was having an affair with a videographer named Rielle Hunter hired by the campaign, Young gained widespread notoriety when he claimed to be the father of Hunter's unborn child and then welcomed Hunter into the home he shared with wife, Cheri, and their three young children.

Senator Edwards first admitted to an affair with Rielle Hunter during an August 8, 2008 "Nightline" interview with Woodruff. In the days and months that followed, he consistently denied being the father of Hunter's baby � that is, until last week -- when Edwards issued a public statement acknowledging that he is the father of Frances Quinn Hunter.

More of Bob Woodruff's exclusive interview with Andrew Young will air later in the evening on "Nightline," and George Stephanopoulos will have Young's first live interview on February 1 on "Good Morning America."
