Brian Williams thinks Donald Trump has "driven well past the last exit to relevance." He thinks he is "irresponsible." Brian Williams was not amused by Donald Trump's unraveled tweeting.

Hesitant to share the Twitter rant with viewers (did BriWi lose a commercial break bet with some unforseen producer?), Williams did not look pleased to be reporting the story at all. Williams, ever the cool cucumber, is clearly annoyed with both the segment and Trump.

Fingers crossed for a Victoria Jackson follow up.
