with that being on his mind facts relating to the russia investigation. i would look for a couple of things. one, whether or not donald trump has some reaction and talks in a way that could be used against him in the future, because bob mueller would do that. and the second thing i would look at is to see if the president of the united states is sending some kind of message to the potential defendant or other witnesses. and that that's in two categories. one, is he sending a message of intimidation some way, through himself or his cohorts, suggesting that people should not be talking and people should keep their mouths shut, which happens in life, from time to time. and the second thing is whether or not he sends a message of reassurance. we also have an historical record in recent months that donald trump will avoid going through the regular process for pardoning someone who's an ally, in this case it was joe arpaio, the sheriff in arizona, and there has been much speculation about whether or not donald trump would hesitate to use his pardon power to get out of legal jeopardy and trouble any allies of his.
