Sessions recused himself from all things Russia, including Special Counsel Mueller's investigation.  Thus, dirty Rod Rosenstein has been running it & we've seen him slow-walk docs, stonewall & refuse to appear before committee.  With Sessions out, POTUS has appointed Whittaker as acting AG - thus HE now has the power over Rosenstein & whether to release FISA declassified documents...something Rosenstein has not done.  Once those come out, the corruption/collusion of Dems is made public and the avalanche has truly started.  As the snow rolls down the mountain, many more corrupt members of Congress will be swept up.
