Trump whines about 'cost of rebuilding' Puerto Rico -- and gets resoundingly destroyed by San Juan's mayor

The mayor of San Juan, Puerto Rico on Friday shot back at Donald Trump after the president argued “big decisions” have to be made about the cost of rebuilding the island, which is still reeling from a lack of basic necessities over a week after Hurricane Maria hit.

“The fact is that Puerto Rico has been destroyed by two hurricanes,” Trump wrote on Twitter. “Big decisions will have to be made as to the cost of its rebuilding!”

San Juan Major Carmen Yulín Cruz, who’s been critical of the administration’s response in Puerto Rico, took issue with Trump’s comment Friday, telling CNN, "If we let them die, nobody is going to pay the debt!”

One of Trump’s first remarks in response to the devastation in Puerto Rico was to complain about the “massive debt” owed by the U.S. territory.

“Texas & Florida are doing great but Puerto Rico, which was already suffering from broken infrastructure & massive debt, is in deep trouble..” Trump tweeted Monday.

Despite the president’s apparent focus on the “debt” and “costs” associated with an island that’s home to 3.5 million American citizens, the Trump administration has been adamant that the federal relief efforts are in full force. On Thursday, Homeland Security Secretary Elaine Duke said she’s “very satisfied” with the administration’s efforts.

“I know it is really a good news story in terms of our ability to reach people and the limited number of deaths that have taken place in such a devastating hurricane,” Duke said

Cruz on Friday rejected Duke’s assessment, telling CNN’s Alisyn Camerota, “Dammit, this is not a good news story.”

"This is a 'people are dying' story," she said.
