Based on his behavior

its hard not to infer that The President is as Guilty as Sin with respect to the Mueller investgation.  But when it comes to obstruction of justice though, he is just so momumentally stupid at it, he makes threats he can't back up, schemes in public and seems woefully ignorant of even the elementary school basics of how the US Constitution works.  In fact the more Trump struggles and flails, the more evidence he piles up of his own guilt.  Literally, the only thing keeping him in the Oval Office is Paul Ryan & Mitch McConnell's zealous commitment to enabling the President right to the edge of National Annihilation.
