Leaders of the conservative Republican Study Committee voted Thursday to oppose last year's spending bill, throwing the House GOP's budget plans into turmoil.
The RSC is the most powerful caucus of House Republicans and includes 170 of the House GOP's 246 members.

Last year's agreement has remained unpopular among the party’s fiscal hawks even after a majority of House Republicans voted to confirm it last fall.
Some members of the RSC had already urged Ryan to break last fall’s unpopular accord.
The vote took place the same day that Flores met with Ryan, as well as the chairmen of the conservative House Freedom Caucus and the moderate Tuesday Group, to discuss the budget.
One day earlier, the full House GOP caucus met to discuss the budget.
Flores told The Hill after that meeting that he had expected to hear a "comprehensive" budget proposal from House Budget Committee Chairman Tom Price (R-Ga.) at that meeting, but did not receive one.
Flores has previously said he would seek a lower spending limit, and said as recently as Wednesday that he is keeping his options open.
Price earlier this week said that his budget proposal would stick by the spending caps, which amount to about $30 billion more spending than the previous year. He promised a vote on that proposal would be coupled with a vote on a bill to trim the deficit sometime this year.
Publicly, Ryan and other GOP leaders did not commit to that idea, and instead reiterated that the decision would be made by the full caucus. Ryan said as recently as Thursday that the party did not have to pass a budget.
This is the first time many House Republicans are drawing a line in the sand on this year’s budget process. Until now, most rank-and-file members have held their fire as Price and the Budget Committee have offered options on how to keep the spending levels in tact.
The opposition from the Republican Study Committee severely compromises the GOP’s efforts to pass a joint budget resolution, which would allow them to begin the appropriations process and achieve what Ryan calls “regular order.”
