The G.O.P. bill would extend tax cuts and almost certainly make big reductions to programs serving the poor. Passing it may be hard, though.

The U.S. Senate passed a Republican bill promoting President Donald Trump's immigration, energy and defense policies in the early hours of Friday morning, despite Trump's preference for a House of Representatives version of the bill that would include trillions of dollars in tax cuts.

The Senate is pursuing a “skinny” spending bill that addresses the president’s priorities for border, defense, and energy spending but leaves other matters for later.
