No, that wouldn't have been successful--the context of the question was thT he was a defendant in a sexual harassment lawsuit; as with any other type of suit, the plaintiff is entitled to investigate similar incidents where the defendant might have behaved similarly. It's really no different than asking the drunk driver that hit your mother about the rest of his driving record.
Now, if he had answered, "Yes, she came on to me, and I happily took what she offered. We did it all over the oval office every night that week, and I'm glad e did," it would have shut down the line of questioning and pretty much ended everything there--it wouldn't have been the similar conduct Jones' attorneys had been looking for.
