The House has approved a new $1.1 trillion spending bill that would avoid a government shutdown at least through September. The bill passed with overwhelming support, signaling a potential end to the bipartisan dispute that forced the government’s two-week closure last year. In a defeat for the tea party, the bill would increase spending by $45 billion over the cuts that would have been forced by the sequester. But it preserves several key Republican demands, including increases for the military, the defunding of high-speed rail projects, and a ban on spending to hold Guantánamo Bay prisoners in the United States.
