Approval of the Republican budget plan left major questions about tax cuts and spending reduction for another day.

Republicans’ budget blueprint cleared the Senate, but a Democratic amendment marathon aimed to put GOP lawmakers on the record regarding potential Medicaid cuts and other politically sensitive issues.

The Senate passed a $340 billion budget resolution early Friday after Democrats forced a marathon "vote-a-rama" in which Republicans had to reject numerous amendments.

Before adopting Republicans’ budget resolution, senators engaged in an all-night parliamentary marathon that Democrats used to try to force the G.O.P. into politically damaging votes.

The Senate is set for an overnight marathon voting session Thursday, known as a vote-a-rama, as Republicans look to clear a key hurdle in delivering on President Trump’s legislative agenda.
