I think Trump should declassify everything related to the Russia investigation. All of it. Pull the "sources" out of the field, give them new identities, whatever one does to protect "sources" when their covers are blown, and dump it all into the public venue. All of it. There's nothing going on in this area of "intel" "methods and sources" worth saving in my opinion. All it's being used for is to illegally spy on Americans, terrorize our own citizens involved in campaigns, violate their civil rights, jeopardize foreign relations, and cost US taxpayers a fortune trying to chase down and get to the bottom of their shenanigans.
