isn't there an obligation by the president to actually assert the constitutional authorities that have been given when accused of something, a crime or anything else? >> i think president obama has invoked too broadly. but on the other hand he has actually released a lot of information. i've been friends with bill barr for a long time. we disagree on executive privilege. i'm a madisonian scholar. i tend to favor congress in disputes. he's the invert. his natural default is article two. my natural divert is art one. but he has released as much information as any in my lifetime including the mueller report. >> that's something that's again not pointed out when you're doing a back and forth like we're doing. the transcript of the call released, the things that have been released in the mueller.
