I only managed to catch a bit, but it looks like he's alternating between taking Trump's advice of trying to be angry and attack his accusers, and tearing up.

Whether that tearing up is because he's putting on a show, or because he watched Dr Ford's testimony and is starting to recognize the damage he's done, I can't be sure, but he's definitely conflicted sitting up there.

It's like he wants to defend himself, but knows that what he did is indefensible.
