Lawyers argue over sex tape at Edwards trial

Edwards is accused of directing a conspiracy to use about $1 million in campaign donors' payments to help hide the Democrat's pregnant mistress as he sought the White House in 2008. He denies knowing about the money and has pleaded not guilty.

Former aide and confidante Andrew Young testified this week that he deposited the payments from a wealthy Texas lawyer who served as Edwards' campaign finance chairman and an elderly heiress into personal accounts controlled by him and his wife. The money was used to help build a $1.5 million North Carolina home; Young, who is testifying under an immunity agreement, said he did not pay income taxes on the money.

Prosecutors objected Friday when a defense lawyer for Edwards asked Young whether he had threatened to release a "private video" to expose Edwards' affair with Rielle Hunter.

U.S. District Court Judge Catherine C. Eagles instructed Edwards lawyer Abbe Lowell to continue his cross-examination of Young without mentioning the tape.

After conferring with the judge, Lowell said he would wait to potentially discuss the tape when the defense presents its case.

Hunter sued Young in state court two years ago over ownership of the sex tape and other personal items in Young's possession. That civil suit was settled earlier this year with an agreement to destroy all copies of the tape, though there are suggestions in court documents that federal investigators may still have a copy.

Defense attorneys had no intention of showing the tape to the jury, but wanted to mention it in the context of the allegation that Young threatened to out Edwards' affair with Hunter in an August 2008 conversation on a dead-end road near Edwards' Chapel Hill estate.

Young was the first witness called by prosecutors and earlier this week testified about the conversation. Young had said Edwards was acting nervous and that "at one point I feared for my life," he testified Friday.

Confronted with copies of his amended tax returns for 2007 and 2008, Young acknowledged that he had used about $1 million of $1.2 million in the payments from Rachel "Bunny" Mellon and lawyer Fred Baron for himself.
