“The hardest thing now is figuring out what can get 51 votes in the Senate,” said Stephen Moore, who was a top economic adviser to Trump during the campaign and who has urged the White House to move more quickly.

Congress also faces an increasing number of legislative distractions that could further imperil Trump’s agenda. There is a big divide among Republicans over whether they can vote to pass a budget resolution in the coming months, and failing to do so could make it much more difficult to change the tax code. In addition, White House officials are now demanding that Congress vote to raise the debt ceiling before the August break — pressing members to take a difficult vote before they head back to their districts…

White House officials plan to push Senate Republicans in June to vote on a repeal of the Affordable Care Act, and they want to spend the rest of the summer whipping up support for major tax cuts. They are also planning to push lawmakers soon to consider an infrastructure package, although that effort has also moved more slowly because his staff hasn’t put together a final plan.

Each of these efforts has stalled either in the White House or in Congress, but Trump has pinned much of the blame on Senate Democrats. White House press secretary Sean Spicer said the president’s “frustration” was that the White House’s big-ticket items have bogged down because of Democrats’ ability to block measures using filibuster rules. Republicans control 52 of the Senate’s 100 seats, requiring them to get support from Democrats on many issues.
