BOTH houses have to pass ALL bills [with the EXACT same language]. If there are any divergences, then it goes to bicameral committee to be hammered out - then a second vote in both houses. After that [if the SAME bill is passed in BOTH Houses], it goes to the President for signature.
BTW: If a bill is a REVENUE bill - it MUST ORIGINATE in the House ...
That’s reassuring, thanks. It’s make or break time for America on this one. I’m not counting on anything after so many frickin’ disappointments.
