Update: The latest news as of 10 AM is that the House is close to a bill that will reopen government and raise the debt ceiling temporarily. Here is the kiddish "Yes, but". It would prohibit extraordinary measures by Treasury. That's a poison pill. I'm not sure they can be stopped. That contradicts the idea of prioritization, which "default deniers" in the GOP have tried to use to play both sides of the arguments.
A White House spokeswoman said that the president would reject the House bill because the add-ons are still a kind of ransom. But the provision requiring Congress to pay individual rates for its own health insurance sounds reasonable enough to me. Maybe break into multiple bills?
Update 2: I can't keep up with all these versions of the House bills and the poison pills. We can do without Nancy Pelosi's saying "The House vote will be a vote for default." Please!
