So where should U.S. Attorney John Durham start as he investigates the Trump-Russia investigation? Well, he might start by talking with former prosecutor Andrew McCarthy. Then: You want to get into the Trump-Russia weeds? This is the place. What about the CIA’s involvement in starting the investigation? How come we don’t hear much about that? Did the FBI, with Carter Page warrant, surf the “upstream part of the Internet” for Trump info? And what about that 2-hop thing? That and more from a man who really knows his Trump-Russia stuff.
