I'm glad he's saying something, but the time to say something was about seven years ago. Once the pattern had begun to establish itself. BIG STINK should have been made about it starting back then.
Anybody remember how the Obamas reached out right at the beginning of his first term? There was news that they wanted to bring back the cocktail party. They wanted to host cocktail parties at the White House for their fellows in Washington DC. Where House and Senate folk could fraternize with the White House in an easier, less-formal social setting and get to know each other and maybe start forming possible alliances. No go. It failed. NOBODY came. It was a public embarrassment leveled at the White House from these selfish closed-minded, sore-loser assholes.
Anybody remember how the Obamas extended invitations to come to the White House for numerous occasions - watching the NCAA finals, watching Oscar screeners before Academy Awards night? NOBODY came. Invitations to state dinners with visiting VIPs and international celebrities and heads-of-state. Turned down. I vaguely recall somebody asking John Boehner about it after one of these and he responded with some pride that he had decided not to accept his invitation. On "principle." 
They absolutely turned their backs to him. DELIBERATELY. From the time they all met in a secret huddle on Inauguration night when everybody else was partying at the various inaugural balls. These assholes, Mitch McConnell, Eric Cantor*, Dan Lundgren*, Kevin McCarthy, Jeb Hensarling, Pete Hoekstra*, Paul Ryan, Tom Coburn*, Jon Kyl, John Ensign*, Pete Sessions, Jim Demint*, Newt Gingrich, Frank Luntz, and Bob Corker. All sequestered together in this little coven-meeting, devising a strategy to say "no" to EVERYTHING President Obama put forward, even if it was something the CONS actually wanted. Objective: To make him a one-term President. These assholes were determined FROM THE START to ruin his Presidency. SO glad it failed. The names with * are those who aren't in Congress anymore, either because they were defeated or stepped down on their own - or in John Ensign's case, in disgrace. I printed out a list several years ago and it's taped to my bedroom wall with other notes and important stuff I don't want to forget.
On edit - I went back and BOLDED each of their names, because I don't want ANY of us to forget, either.
