WASHINGTON — Democrats say the full House won’t vote on sweeping health care legislation until September.

It’s part of a three-way deal between conservative Democrats, House Speaker Nancy Pelosi and the White House.

Under the deal, the last of three House committees will be able to finish work on the legislation this week. But lawmakers will have time to review the 1,000-page bill before a floor vote in September. Originally, Pelosi wanted the House to vote by the end of this week, before the monthlong August break.

Rep. Mike Ross of Arkansas, one of the conservative Democrats, said the deal trims the legislation’s cost, protects small businesses and rural hospitals, and ensures that any government-sponsored insurance option competes fairly.
