The two men were involved in a panel discussion about the movie "Wag the Dog" (which Hoffman stars in), and Oliver was the moderator. He kept bringing up the sexual harassment charges against Hoffman, and it got incredibly testy.
The Washington Post has the story.
When I was with Steve & Garry's show they always said, "if it can't be funny, then it better be awkward". People remember awkward. Sounds like anybody who was in this room won't forget this panel discussion.
