RECONCILABLE DIFFERENCES: The Senate has passed Republicans’ megabill by the narrowest of margins, bringing President Donald Trump and the GOP much closer to a landmark victory that would lower taxes, beef up border and military spending, slash the social safety net, damage the clean-energy boom, balloon the deficit and raise the debt ceiling.

Majority Leader John Thune (R-South Dakota) conceded early Tuesday that he did not know if he had the votes yet to pass the measure.

The finish line will come after a whirlwind of votes, nicknamed a "vote-a-rama," on what are expected to be dozens of amendments.
