The president's tweets set off a flurry of chatter online, given that the US territory is barely entering its third week with the majority of the population still without power and one-third without water. Electric and all infrastructure was disaster before hurricanes.
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.
"He wrote in two separate tweets, "'Puerto Rico survived the Hurricanes, now a financial crisis looms largely of their own making.' says Sharyl Attkisson. Reassuring the island, Kelly said the US will "stand with those American citizens in Puerto Rico until the job is done".
While the Trump administration requested $29 billion in supplemental spending last week, it asked for additional resources Tuesday night, including $4.9 billion to specifically to fund a loan program that Puerto Rico can use to address basic functions like infrastructure needs.
Forty-five deaths in Puerto Rico have been blamed on Maria, about 85 percent of Puerto Rico residents still lack electricity and the government says it hopes to have electricity restored completely by March.
"The people of Puerto Rico are American citizens and they deserve federal assistance to recover and rebuild", Jennifer Hing, a spokeswoman for House Appropriations Committee chairman Rodney Frelinghuysen, said in a statement to Anadolu Agency.
The mayor tweeted that Trump is "incapable of fulfilling the moral imperative to help the people of PR. Shame on you!"
Celebrities and politicians have responded to the threat by arguing that Puerto Rico needs more aid, not less (obviously).
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 words were taken by some as a hint at abandoning Puerto Rico.
Trump's tweets come three weeks after the hurricane first struck the island, which remains largely without power.
Cruz's comments were likely in response to early morning tweets Thursday from the president, where he said Congress needs to act quickly to provide relief because "FEMA, the Military & the First Responders, who have been awesome (under the most hard circumstances) in P.R. forever!"
Thursday's hurricane aid package totals $36.5 billion and follows a $15.3 billion measure that passed last month. Ryan is set to visit Puerto Rico on Friday. For now, it ignores huge demands from the powerful Florida and Texas delegations, which together pressed for some $40 billion more.
