collusion. obstruction of justice can t be charged against a sitting president for exercising his authority under article two ofof the constitution. but if i were the president, i would be concerned about the southern district of new york, which is probably why he brought rudy giuliani onto his team, who was this former attorney in the southern district of new york. as i have told clients for 53 years, you can t have any confidence that your best friend, your brother, your sister in, won t flip if the government charges them with serious crimes. you can charge them with a series of crimes that results in life in prison. the pressure is intense. and then, the pressure is not only to sing, but to compose, because what happens is a witness knows that he ll get a better deal if he can elaborates if he can make up stories, if he can tell the government what the government wants to hear. that may not always be the c truth. so i don t think that president trump is out of the woods yet.
