WASHINGTON (AP) — President Donald Trump lashed out at hurricane-devastated Puerto Rico on Thursday, insisting that federal help will be limited and blaming the U.S. territory for its financial struggles. The broadside came as the House headed toward passage of a $36.5 billion disaster aid package, including assistance for Puerto Rico.

Puerto Rico has been reeling since Hurricane Maria struck three weeks ago, leaving death and destruction in an unparalleled humanitarian crisis. Forty-five deaths in Puerto Rico have been blamed on Maria, 90 percent of the island is still without power and the government says it hopes to have electricity restored completely by March.

Trump tweeted: "We cannot keep FEMA, the Military & the First Responders, who have been amazing (under the most difficult circumstances) in P.R. forever!"

In a series of tweets, the president said "electric and all infrastructure was disaster before hurricanes." He blamed Puerto Rico for its looming financial crisis and "a total lack of accountability."

Democrats said Trump's attacks were "shameful," given that the 3 million-plus U.S. citizens on Puerto Rico are confronting the kind of hardships that would draw howls of outrage if they affected a state. One-third of the island lacks clean running water and just 8 percent of its roads are passable, according to government statistics.

"It is shameful that President Trump is threatening to abandon these Americans when they most need the federal government's help," said Maryland Rep. Steny Hoyer, the second-ranking House Democrat.

The legislative aid package totals $36.5 billion and sticks close to a White House request. For now, it ignores huge demands from the powerful Florida and Texas delegations, which together pressed for some $40 billion more.

A steady series of disasters could put 2017 on track to rival Hurricane Katrina and other 2005 storms as the most costly set of disasters ever. Katrina required about $110 billion in emergency appropriations.

The bill combines $18.7 billion for the Federal Emergency Management Agency with $16 billion to permit the financially troubled federal flood insurance program pay an influx of Harvey-related claims. An additional $577 million would pay for western firefighting efforts.

Up to $5 billion of the FEMA money could be used to help local governments remain functional as they endure unsustainable cash shortfalls in the aftermath of Maria, which has choked off revenues and strained resources.

House Speaker Paul Ryan, R-Wis., planned to visit Puerto Rico on Friday. He has promised that the island will get what it needs.

"It's not easy when you're used to live in an American way of life, and then somebody tell you that you're going to be without power for six or eight months," said Resident Commissioner Jenniffer Gonzalez-Colon, who represents Puerto Rico as a nonvoting member of Congress. "It's not easy when you are continue to suffer — see the suffering of the people without food, without water, and actually living in a humanitarian crisis."

The GOP-run Congress had protracted debates last year on modest requests by former President Barack Obama to combat the Zika virus and help Flint, Michigan, repair its lead-tainted water system. Now, it is moving quickly to take care of this year's crises, quickly passing a $15.3 billion measure last month and signaling that another installment is coming next month.

Several lawmakers from hurricane-hit states said a third interim aid request is anticipated shortly — with a final, huge hurricane recovery and rebuilding package likely to be acted upon by the end of the year.
