WASHINGTON—Republican senators are making a mad dash to pass the GOP tax-and-spending megabill and send it to President Trump’s desk by July 4.Senate Republicans cleared the first procedural hurdle late Saturday by a 51-49 vote.

The Senate parliamentarian struck down several key provisions in President Donald Trump's major tax and spending bill.

While much of the focus on President Donald Trump’s “big, beautiful bill” is on tax breaks, immigration and health insurance, the sprawling budget deal is also expected to overhaul how the government handles student loans.
