WASHINGTON (AP) — Past its own New Year's deadline, a weary Congress sent President Barack Obama legislation to avoid a national "fiscal cliff" of middle class tax increases and spending cuts late Tuesday night in the culmination of a struggle that strained America's divided government to the limit.

The bill's passage on a bipartisan 257-167 vote in the House sealed a hard-won political triumph for the president less than two months after he secured re-election while calling for higher taxes on the wealthy.

Moments later, Obama strode into the White House briefing room and declared, "Thanks to the votes of Republicans and Democrats in Congress I will sign a law that raises taxes on the wealthiest 2 percent of Americans while preventing tax hikes that could have sent the economy back into recession."
