Congressional Republicans left Washington riding high after their big victory on government spending. Now they’re returning to face a brutal reality check: Their legislative agenda is going nowhere fast.

Now months into the process, House and Senate Republicans are still trading barbs and accusing each side of slowing down progress on President Donald Trump’s top legislative priority — a sweeping bill linking a tax overhaul to energy, defense and border policies.

When GOP lawmakers return to Washington Monday, they will be under fierce pressure to show meaningful progress toward delivering on that agenda in the narrow, three-week window they have before leaving town again. Speaker Mike Johnson has set an ambitious goal of finalizing a budget blueprint with the Senate and getting it passed in the House by the week of April 7.

Yet nearly every key decision remains unsettled. They include how deep to cut into social safety-net spending, how to placate swing-seat lawmakers over a key tax break, how to account for the cost of extending existing tax cuts and how many more breaks they can pile on top.
