WASHINGTON — The House on Friday passed a $19 billion disaster aid bill that would deliver long-sought relief to farmers and victims of hurricanes and floods, and rebuild southern military bases, as Democrats try to dislodge the legislation from a Senate logjam over aid to hurricane-slammed Puerto Rico.

The measure passed by a 257-150 vote over the opposition of most Republicans, who said it should also include the Trump administration’s $4.5 billion request for stepped up humanitarian aid and law enforcement along the U.S.-Mexico border, which is facing a wave of migrants fleeing violence in Central America.

The House had passed a $14 billion version of the measure in January, but the legislation has been held up in the Senate amid a fight between President Donald Trump and Democrats over aid to Puerto Rico. Trump is feuding with Democratic officials on the island and falsely claims that Puerto Rico has already received $91 billion in aid.

Trump tweeted Thursday to urge Republicans to vote against the bill. “House Republicans should not vote for the BAD DEMOCRAT Disaster Supplemental Bill which hurts our States, Farmers & Border Security,” Trump tweeted. “We want to do much better than this. All sides keep working and send a good BILL for immediate signing!”

After the vote, Trump tweeted in praise of GOP solidarity, although 34 Republicans broke with his position and supported the bill. “Great Republican vote today on Disaster Relief Bill. We will now work out a bipartisan solution that gets relief for our great States and Farmers. Thank you to all. Get me a Bill that I can quickly sign!” Some Republicans who broke with Trump were from areas hit by the disasters, like Texas and Florida; others were moderate Republicans from the Northeast.

Disaster aid measures are usually among the few reliably bipartisan pieces of legislation left in an increasingly partisan Washington. But the pending measure faces several obstacles in addition to the battle over Puerto Rico, including an attempt by powerful Senate Appropriations Committee Chairman Richard Shelby, R-Ala., to boost Army Corps of Engineers harbor dredging efforts, of which the Port of Mobile in his state would be a major beneficiary. Shelby’s relationship with White House Acting Chief of Staff Mick Mulvaney also appears strained.

Since the House measure originally passed, Midwestern floods have added billions of dollars to the government’s roster of disaster needs, while a rising wave of Central American migrants seeking refuge is requiring additional billions of dollars to house and care for thousands of migrants.
