Transcript for Why did Mueller stop short of concluding obstruction?
Let's get right to Dan Abrams, watching this all day long with us. And Dan, I wanted to get to that line from Robert Mueller today, it got a lot of attention. He said, if we had confidence after a thorough investigation the president clearly did not commit obstruction of justice, we would say so. We are unable to reach that judgment. They were unable to clear him. What did we learn in this 448-page report that helped answer that question why? Reporter: There are two broad reasons. One, it's hard to find obstruction of justice when you're talking about a president who has got wide power and authority, for example, to fire someone.

I think it is also clear, though, that there is a divide between Robert Mueller and the attorney general on the issue of obstruction of justice. And you even heard William Barr talk about the fact that he did not agree with some of the legal theories that Robert Mueller was using. Clear when up read the report that Mueller thinks that there was evidence of obstruction, specifically on particular instances. Barr made it clear he looks at it all, he does not think there's obstruction. That was the first view of a potential break between the two. Reporter: Absolutely. Dan, thank you.
