John Edwards Aide: John Wanted Mistress to Abort Baby

In a new ABC interview Andrew Young, a former aide to John Edwards, makes explosive allegations -- including that Edwards wanted his mistress to abort their baby and that Young saw a sex tape starring the former presidential candidate.

Young told ABC News' Bob Woodruff that after Edwards learned that his mistress Rielle Hunter was pregnant, "the senator tried to convince her to have an abortion. ... He tried to convince me to convince Rielle to have an abortion."

Young also told Woodruff that Edwards was not sure if Hunter's baby was his because, according to Edwards, Hunter was a "weird slut and a freak."
