To be sure, President Trump’s conduct outlined on this score isn’t flattering, to put it mildly. For example, the special counsel’s evidence includes indications that the president attempted to induce White House Counsel Don McGahn to fire the special counsel (in June 2017), and then (in January 2018) to deny that the president had made the request.
Mueller’s report further suggests that the president dangled pardons. He made ingratiating comments about Paul Manafort, Michael Flynn and Michael Cohen when they appeared to be fighting the cases against them (and presumably fighting the prosecutor’s efforts to get them to cooperate) but then turned on Flynn and Cohen when they decided to plead guilty and provide testimony for Mueller.
On the other hand, there is evidence that cuts sharply against obstruction. The president could have shut down the investigation at any time, but he didn’t. He could have asserted executive privilege to deny the special counsel access to key White House witnesses, such as McGahn.
[Ed. – Mueller in essence reversed the burden of proof, placing it on the accused — something Democrats are skilled at.]
