back in the day when richard lugar was the republican chair and working with the ranking member joe biden or with john kerry chairing it or biden chairing it, back in previous years there would have been hearings by now on what the heck is going on at the state department, whether it was a republican or a democratic president, to have rudy giuliani running around and running foreign policy, mike pompeo covering up for the president, there's no other way to describe it, yet has anyone, have you been asking your chair to hold public hearings? >> well, listen, i asked chairman risch, the chairman of the foreign relations committee back in may, to conduct an investigation into rudy giuliani's shadow foreign policy. we all knew something was really amiss in and around ukraine back in the spring. there have been requests to the chairman for months now to try to get to the bottom of all of this. as you mentioned, nobody around the world is going to ally themselves with the united states, is going to partner with us in fights against dictatorships and terrorism if they think they'll get pulled in
