See my post # 593 ...
My interpretation of Article I, Section 7 and the Supreme Court case [post #593] is that each bill must have the yeas and nays recorded for it [although SCOTUS has yet to decide this question].
If the "Slaughter Rule" is used, they are folding the Senate Bill into the House Concurrent Resolution, voting on the HCR [that "deems" the Senate bill to have passed], then stripping the Senate bill from the HCR, and then sending to the President for signature.
So, the Senate bill [with NO recorded yeas or nays] ends up on the Preisdent's desk.
Seems to violate article I, Section 7.
