As interesting as Comey's testimony will be, I doubt that we will hear much today that we don't already know. Some of what he wants to say cannot be said in public because of secrecy concerns and might have to reserved for a closed session of the Senate Intelligence Committee. I'm no fan of Trump, but if his opponents in Congress and elsewhere are expecting something from Comey that will encourage the House to move towards an impeachment proceeding, I think they might in for a big disappointment today.
