Senate Judiciary Chairman Lindsey Graham gave some brief remarks to local Dallas media discussing his summer agenda for the Judiciary Committee.  Graham notes he does not intend to question Robert Mueller -deferring to AG Barr- which is not surprising considering how lightly Mueller may have been involved in the investigation.
Graham also notes the separation between the legislative branch and judicial branch as a firewall for inquiry into the FISA court.  However, Graham explains his intent to discuss possible FISA abuse (manipulation from the executive branch) with Chief Justice John Roberts. It appears Graham is also waiting for the DOJ inspector general report.
