these documents in a safe in the context of a broader conversation about document production and different approaches to document production where cobb wanted there to be more disclosure of documents and mcgahn wanted there to be less disclosure or a more careful review of those documents before they were disclosed certainly suggests that ty cobb believed that these documents in the safe were somehow critical and should be turned over to muler and that mcgahn did not. we don't know what these documents are. all we know is there is a potential debate about that. >> as you explain in the piece, ty cobb is more of the school of thought let's just turn it all over and get this thing over with more quickly which is in contrast to what don mcgahn says. there's also a line in the piece, ken, where you hear talk of, of course, fears or tensions within the white house and so some people are worried that some people may be miked for bob mueller. why?
