fate today. >> are you firing your chief of staff? >> reporter: and as the revolving door spins at the white house, those who no longer work there are still giving the president headaches. >> to go to work for a man who is pretty undisciplined, doesn't like to read, doesn't read briefing reports, doesn't like to get into the details of a lot of things, but rather just kind of says, look, this is what i believe. and you can try to convince me otherwise. >> reporter: now, jake, rex tillerson also said the president is essentially ignorant of the laws and it didn't take the president long to respond to that criticism. he tweeted not too long ago while on air force one on his way back to washington from kansas city, praising mike pompeo, who succeeded rex tillerson at the state department, but also adding that rex tillerson didn't have the mental capacity needed. he was dumb as a rock, and i couldn't get rid of him fast enough. he was lazy as hell.
