WASHINGTON — The Senate on Thursday overwhelmingly backed a $15.3 billion aid package for victims of Harvey and increased America's borrowing authority to fund the government into December.

The 80-17 Senate vote sends the package to the House for a vote on Friday. With emergency accounts running out of money and Hurricane Irma barreling toward the East Coast, the measure appears set to easily pass.

The legislation also would provide money to government agencies through Dec. 8, eliminating the threat of a government shutdown when the new fiscal year starts next month.

Thursday's vote came a day after President Donald Trump stunned GOP leaders by siding with Senate Democratic Leader Chuck Schumer of New York and House Minority Leader Nancy Pelosi, D-Calif., by backing a three-month extension to the debt limit increase.

House Speaker Paul Ryan, R-Wis., had urged a longer extension, but Ryan backed the idea on Thursday, telling reporters that the president didn't want to have “some partisan fight in the middle of the response.”

The aid money comes as Harvey recovery efforts are draining federal disaster aid coffers and Irma is taking aim at Florida. It's just the first installment on a recovery and rebuilding package for the twin hurricanes that could eclipse the more than $110 billion cost to taxpayers of Hurricane Katrina.

Senate Majority Leader Mitch McConnell added $7.4 billion in rebuilding funding to Trump's $7.9 billion request to deal with the immediate emergency in Texas and Louisiana.
