If you interpret his comment about firing... Comey... If you interpret that as obstructing the investigation, as opposed to removing a guy who was doing a bad job, on the recommendation, in part, of( Deputy Attorney General Rod) Rosenstein, but you see it as obstructing the investigation, then you can say it is obstruction, and then you can say it is perjury, which is even easier for them, which is where I think, if they are sneaky, they are going.
