Thanks to expeditious and disciplined action by House Republicans, the White House is on track to see President Donald Trump’s “big, beautifull bill” pass Congress before the July 4 recess. House Speaker Mike Johnson (R-LA) has told senators he can’t promise final passage if they make serious revisions to the legislation, but Trump has said he expects “fairly significant” changes as the Senate works through June.

While the House bill is a real accomplishment, it is far from perfect and can be significantly improved by the Senate. Unfortunately, there is a danger that the Senate might make it worse, and there appear to be hard limits on Senate improvements. It would be wise for the Senate to tweak what the House has done instead of attempting a full-scale rewrite.
