I also stand corrected, because I thought the porn videos pertained to Bork.I stand corrected. I don't remember that, perhaps because, as the Wikipedia article on him put it,
"His video rental history was unremarkable, and included such harmless titles as A Day at the Races, Ruthless People, and The Man Who Knew Too Much. "
The incident I remembered was this one, from the Wikipedia article on Clarence Thomas' nomination.
"According to Mayer and Abramson, soon after Thomas was sworn in, three reporters for The Washington Post "burst into the newsroom almost simultaneously with information confirming that Thomas' involvement with pornography far exceeded what the public had been led to believe."[63] These reporters had eyewitness testimony and video rental records showing Thomas' interest in and use of pornography.[64] However, according to Jeffrey Toobin, because Thomas was already sworn in by the time the video store evidence emerged, The Washington Post dropped the story."
There had been rumors of his video rental habits during the hearing, but the committee wouldn't entertain those rumors openly. (I won't vote for Biden in the primaries because he's too darned old, but I've voted for him in the past, and I really respected the way he handled the Thomas hearings.)
I don't share your opinion of how Biden handled the proceeding, but it's been too many years and my memory is sketchy.
