That Fox News Story about Obama introducing a smaller "new health care bill" turns out to be misleading. Pelosi's spokesman tells The New Republic's Jonathan Cohn:
The Speaker was referring to the compromise between the House and the Senate that the President unveiled last week--not a new smaller bill. As she has said repeatedly, she is committed to passing comprehensive health insurance reform.
So, there's no new bill. The House will have to pass the Senate bill, and then pass a reconciliation "sidecar" to make some changes, trusting that the Senate will follow through. It seems that Pelosi and the White House are just spinning this as something new.
