GOP agenda already stalling in Congress

After moving to start rolling back the Affordable Care Act just days after President Trump was sworn in last month, Republican lawmakers and Mr. Trump have yet to deliver on any of the sweeping legislation they promised. Efforts to come up with a replacement for the health care law have been stymied by disagreements among Republicans about how to proceed. The same is true for a proposed overhaul of the tax code.

The large infrastructure bill that both Democrats and Mr. Trump were eager to pursue has barely been mentioned, other than a very general hearing to discuss well-documented needs for infrastructure improvements. Even a simple emergency spending bill that the Trump administration promised weeks ago — which was expected to include a proposal for his wall on the Mexican border — has not materialized, leaving appropriators idle and checking Twitter…

“On our side, it’s pretty clear who drives policy,” said a Republican aide who spoke on the condition of anonymity to avoid being written about by Mr. Trump on Twitter. “But take any issue and try to figure that out from their side.”

Is the leading influence Mr. Trump’s policy adviser, Stephen Miller, who presents himself as the voice of the White House? Or the president’s son-in-law, Jared Kushner? Or Vice President Mike Pence? No one seems to know.
