What the Republicans just did

From John Cassidy, writing in the New Yorker:

Ryan and his sidekick, the House Majority Leader Kevin McCarthy, pushed through a bill that, if it ever goes into effect, could upend one-sixth of the American economy and result in tens of millions of Americans losing their health coverage. Since the Republicans failed to give the Congressional Budget Office time to “score” the bill before voting on it, we don’t have any official estimates of its likely effects. But the bill that was passed on Thursday was an amended version of a bill that the C.B.O. had previously determined would raise the number of uninsured people by twenty-four million over ten years, and increase premiums for many others, particularly the old and the sick, as well.

The Bill now goes to the Senate. What will happen there?
