WASHINGTON — The House approved a two-year budget deal Wednesday as retiring House Speaker John A. Boehner sought to quell the bitter budget battles that defined his tenure and provide a smoother transition for his likely successor, Rep. Paul Ryan.

The $80 billion bipartisan accord between congressional leaders and President Barack Obama reverses steep spending cuts to defense and domestic programs, and staves off hits to Medicare and Social Security Disability benefits.

First District U.S. Rep. Tim Walz, D-Minnesota, voted for the agreement.

“While no budget agreement of this magnitude is ever perfect and there are things I would do differently, I supported the agreement today in the interest of our economic stability as a nation,” Walz wrote in a statement.

The deal also raises the federal government’s borrowing limit through March 2017, well after the presidential election.

The bill passed 266-167. Every Democrat voted for the deal, as did 79 Republicans.

Most GOP lawmakers voted no. The Senate is expected to approve the deal in coming days.

“We’re pleased,” said House Minority Leader Nancy Pelosi, D-Calif. “It’s a compromise.”

The vote came as Ryan moved closer to becoming the new House speaker Wednesday, winning an internal Republican nominating election for the job he never wanted but is now eager to embrace.

The 45-year-old former GOP vice presidential nominee won the majority threshold by loosely uniting the party’s often-warring wings of conservatives and more mainstream lawmakers.

Behind closed doors, signs of GOP unrest were evident. Ryan won 200 votes, well over a majority of the House GOP, but fewer than the 218 he will need in the upcoming floor vote. Still, even those who voted against him believe he will prevail.

A final floor vote for speaker is set for today.

“The selection of Paul Ryan as our next speaker marks an important step toward unifying our conference,” said Majority Leader Kevin McCarthy, R-Calif., who stepped aside from the leadership race when it became clear he would have difficulty building a cohesive majority.

Boehner wanted to “clean up the barn” for Ryan, believing the $80 billion deal would help end the budget standoffs that stymied much of his own time as speaker.

Ryan, though, said the closed-door deal-making process “stinks.”

The last-minute budget accord between Boehner and the White House left Ryan forced to choose between conservatives who oppose the deal and a bipartisan array of lawmakers who are expected to approve it.

Early Wednesday, Ryan said, he decided there were “few good options” and he would back the deal.

“It’s time for us to turn the page on the last few years and get to work on a bold agenda we can take to the American people,” Ryan said.

Now Ryan, who would become the youngest speaker to take the gavel since 1869, is poised to begin his leadership career at odds with the same far-right faction that forced Boehner out.

The accord pushes most of the budget battles off until after the 2016 presidential election.

But the threat of a possible government shutdown remained as Congress still must pass bills to fund the government at the new spending levels. The first test will come Dec. 11, when current funding expires.
