The first major test of Mr. Trump and his sway over congressional Republicans will come Tuesday morning at 10 a.m. That is when the Congressional Budget Office, the nonpartisan Capitol Hill scorekeeper, will update its budget outlook. The office is expected to say that the federal deficit, after years of decline, will start swelling again this year and will pick up steam over the next decade if policies aren’t changed to curb the growth of health care programs and of Social Security in an aging populace. The annual report could be a major brake on Mr. Trump’s agenda, which includes large increases in spending on infrastructure and defense, as well as deep tax cuts. Those plans could collide with Republican promises to balance the budget — if Republicans care about such niceties in the Trump era.
