The last thing jurors in the John Edwards trial saw today before the prosecution rested was video from a "Nightline" interview that shows Edwards lying.

As the prosecution wrapped up its case, the state used the last 15 minutes or so to play most of ABC's Bob Woodruff's interview with Edwards, in which the former presidential hopeful admitted to having an affair with Rielle Hunter. The interview, which originally aired on "Nightline" in August 2008, was the first time Edwards publicly admitted that Hunter was his mistress, but denied fathering her child.

Edwards was in the courtroom, watching himself on the video as it played. At times, Edwards looked down or put his head in his hands.

Watch part 1 of the 2008 "Nightline" interview here:

And part 2 here:

Edwards is accused of illegally using campaign funds to hide Hunter and the baby. He claims any money he received to hide Hunter was a personal gift and he was motivated only to keep the affair and his daughter with Hunter a secret from his wife, not the government.
