NOPE! Not true. sure he can pick and choose who he wants, but at the same time it is AGAINST THE LAW to interfere with an official on going investigation. So, if the President fired Comey, the head of the official Russian investigation to get a monkey off his back, he obstructed justice. THAT'S THE LAW.....BULL SHIT!It's obstruction of justice if someone interferes with an on going investigation...even when the President does it. He can legally fire and hire for admin positions but he can not fire the head of the on going official investigation simply because he doesn't want the official investigation in to Russia or his campaign team to continue.
The administration can hire and fire with or without CAUSE.. Doesn't matter what might be going on..
And President Trump admitted and told Lester Holt, in his interview, he fired comey due to the Russian investigation....
