A Senate source e-mails:

Right now, the United States Senate stands in recess… WHY? Because the Grand Bargainers (and make no mistake about who these folks are – Republicans hell bent on getting the deal done… ) are working to finalize a 300 plus page amendment (yes I said over 300 pages) which we have not even seen yet. Copies may appear sometime soon, but “only for the Grand Bargainers” until a little later…
If ever there is a time for Senators to be specifically put on the spot for a breach of faith with the American public, it is now… the process is terrible, the substance is terrible and if you think for a minute we should rely on the House of Representatives to stop the bill, think again.
