The president struck a very different tone for Texas or Florida, which he promised to stand with "EVERY SINGLE DAY" shortly after those states were wracked by hurricanes before Puerto Rico and now face long-term recovery efforts.
The House of Representatives is expected to vote Thursday on a bill to provide an additional $36.5 billion for hurricane disaster relief efforts, including in Puerto Rico.
The House is on track to back Trump's request for billions more in disaster aid, $16 billion to pay flood insurance claims and emergency funding to help the cash-strapped government of Puerto Rico stay afloat.
He says at a White House briefing the US will stand with Puerto Rico "until the job is done".
Puerto Ricans are USA citizens., a fact noted by Gov. Ricardo Rossello who wrote on Twitter Puerto Ricans "are requesting the support that any of our fellow citizens would receive across our Nation".
"The Post wrote in its editorial that a majority of the population in Puerto Rico is still without power; many don't have access to clean water".
Democrats said Trump's tweets were deplorable, given that the 3 million-plus USA citizens on Puerto Rico are confronting the kind of hardships that would draw howls of outrage if they affected a state.
The president adds: "We can not keep FEMA, the Military & the First Responders, who have been fantastic (under the most hard circumstances) in P.R. forever!"
In remarks at the White House, Trump said he was taking a step toward "saving the American people from the nightmare of Obamacare".
Maria slammed into Puerto Rico as the island was already struggling with a severe financial crisis, which forced the government to file for bankruptcy in May. The financial situation is more complicated than Trump's tweets suggest.
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.
Nearly $5 billion of the funding could be used to help the government of Puerto Rico and its local jurisdictions stay functional as they endure unsustainable cash shortfalls in the aftermath of Maria.
House Speaker Paul Ryan will lead a bipartisan delegation visiting Puerto Rico on Friday, according to the speaker's office. He has promised that the island will get what it needs.
"We have gone all out for Puerto Rico", Trump said at that meeting with Puerto Rico officials, including Cruz. "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".
