how hard is it to prove obstruction of justice from a president? well, it would be pretty hard especially if we are going from the baseline that maybe mueller wouldn t indict the president as current doj law guidance says. if you were to take the tweets, the actions behind closed doors, the reports of offering pardons for potential key witnesses before they were indicted as the times and the washington post have reported, some believe that mueller could try to build a case, this sort of composite case of obstruction. the same time the president has an enormous power to hire and fire. firing comey may be right within his purview as president. this is why this kind of a case is pretty hard. thanks very much with the latest on that investigation. let s get to more right now.
