Congressional leaders reached a $1.3 trillion spending deal Wednesday to keep government agencies operating through September, unveiling legislation that would make good on President Trump’s promises to increase military funding while blocking much of his immigration agenda. . . . In the broadest strokes, the bill gives Republicans a major win by delivering a $78 billion increase in military spending over 2017 levels, while Democrats won a $52 billion increase for domestic programs. In many instances large spending increases on the domestic side ignored budget cuts proposed by the Trump administration, allowing lawmakers of both parties to trumpet victories on programs from opioid prevention to clean-up of the Great Lakes.
