matters, i think, than anybody who has worked with him in the past appeared to have expected in terms of his appearance today. there had been the justice department threat ahead of today's testimony that mueller shouldn't tread outside the bounds of his report and he shouldn't talk about uncharged third parties and shouldn't talk about any decision-making processes and he did reference those boundaries at times today, but he surely went outside them at times, as well. and he did so in ways that -- it seems to me, point these sort of neon big bright arrows towards what we couldn't and didn't get from him today that it now seems fairly imperative to chase down. given the unrelentingly dire descriptions he gave about the president's conduct and the conduct of the president's campaign and its ongoing implications for the country. seems like they gave us two big directions today that feel imperative in terms of what we try to figure out next and the paths that we next follow to try to get to the bottom of this still open scandal.
