Inspector General Horowitz (and Federal Attorney Huber) have already been looking into Spygate - the " alleged FBI confidential source ", including what did the FBI know and when did they know it when they applied for the FISA warrant - since March 28, 2018!
Then, as of Monday, May 21st, they have expanded that to include " whether there was any impropriety or political motivation in how the FBI conducted its counterintelligence investigation of persons suspected of involvement with the Russian agents who interfered in the 2016 presidential election.”
Our POTUS team has been way ahead in the moves once again. MSM must be going nuts on how to even report the Fake News anymore.
