WASHINGTON (AP) — In a major blow to efforts to get Congress’ troubled budget process back on track, the Senate’s top Democrat yanked a $180 billion spending measure from the Senate floor Thursday after Republicans protested a plan that would have denied them the chance to more easily win changes to the measure.

Majority Leader Harry Reid, D-Nev., pulled the bill after Minority Leader Mitch McConnell, R-Ky., thwarted a move to require a supermajority 60-vote threshold for adoption of amendments to the measure.
