Well, Trump found himself an AG who auditioned for the job by sending Trump a 19 page memo making the ludicrous argument that Trump did not obstruct justice. What’s more, he even concluded that Trump is above the law in this regard. A Nixonian “It’s not a crime if the president does it” fiction. So forget about Trump facing criminal charges for that, at least while Barr is AG.
But the House may well impeach Trump for his obstruction of justice crime wave. They would obviously be boosted in that regard if they had the product of Mueller’s investigation, but Trump and Barr will no doubt do all they can to conceal that. So, it’s just hard to say at this point.
