mr. mcgahn, you don't know 100% of what he testified to, mr. mueller? >> i think that through john dowd, we have a pretty good sense of it. john dowd yesterday said -- i'll use his words rather than mine -- that mcgahn was a strong witness for the president. so i don't need to know much more about that. >> i want to go to nbc's jegeof bennett who's live at the white house. the president on another twitter tear. the "new york times" reporting he's clearly -- "the new york times" reporting clearly has gotten him fired up. what's he saying this morning? >> that's right, chris. this "new york times" reporting has certainly struck a nerve. the president says he has nothing to hide. the president is now adding this tweet to the collection. he says, where's the collusion? when there was no collusion, they say there was obstruction of a phony crime that never existed.
