Tonight, 10/22/2019, Brian Williams played right into the hands of Donald Trump by whining that he didn't have even one inch of tape to show what is going on in the impeachment investigation. Shame on you, Brian. Are you a total idiot? The Democrats have explained very clearly that they are doing closed door investigations right now so as not to allow "collusion" between witnesses and will as soon as possible make records open to the public. This is what Lindsey Graham (and Donald) referred to as a lynching, likewise whining that Donald is not getting a chance to defend himself. I can hardly believe you would say that--but you did. Perhaps you could apologize publicly to Congress in tomorrow night's broadcast, though the damage is done.
You also might consider a more professional way of thanking guests who appear on your program, instead of the "sucking up" approach you use. It is patronizing and belittling to people of stature and expertise.
