WASHINGTON - The US Congress on Thursday approved $38 billion in spending cuts this year as part of a bill to fund the federal government through Sept. 30, sending the legislation to President Barack Obama to sign into law. After months of wrangling between Democrats and Republicans, the Senate voted 81 to 19 in favor of the budget bill for the rest of this fiscal year. Passage came shortly after the House of Representatives voted 260-167 for the measure. Without approval of this bill, US government funding for most agencies would have expired at midnight on Friday.
