Discuss President Trump's relationship with the security agencies in light of his claims about having special knowledge and his reluctance to attend briefings.
Peter, you obviously don't read much news. The security agencies have expressed surprise at Trump's claim that they are delaying when he is the one who won't show up for the briefings. 
After all, he claims that he "knows things that no one else knows."  
The man is a proven liar and con man.
