Trump's outburst came after a day after San Juan's mayor Carmen Yulin Cruz delivered a sharp retort to comments from a top Trump administration official, who said the federal relief effort was a 'a good-news story'.
On the island of Puerto Rico, thousands of people are still in need of food, water and power in the wake of Hurricane Maria. White House spokeswoman Sarah Sanders said Thursday that 10,000 federal government relief workers were now in Puerto Rico, including 7,200 troops, and that 44 of the island's 69 hospitals were now fully operational.
As though criticizing Mayor Cruz wasn't crass enough, Trump invoked the racist trope of lazy minorities hungry for government handouts just for good measure. New Jersey emergency response personnel will spend at least six weeks in Puerto Rico and could stay longer if more help is needed.
"The FEMA and this administration was not ready", she said.
A few hours after posting her message to Trump, Rihanna called for a "round of applause" for efforts to aid Puerto Rico from former presidents George H.W. Bush, Barack Obama, George W. Bush, Bill Clinton and Jimmy Carter.
Another video sent from Rihanna, who was born and raised in Barbados, to the president saw San Juan's mayor crying over the "humanitarian crisis" in the country.
The president has been accused of not acting quickly enough to send aid to the United States territory, which was left without electricity and in crisis by Hurricane Maria. Cruz had previously accused the Trump administration of "killing us with the inefficiency".
Miranda tweeted in response, "You're going straight to hell, @realDonaldTrump".
He also noted that he and the first lady will be traveling to Puerto Rico and possibly the U.S. Virgin Islands, which were also hit by hurricanes.
"I know it's a hard storm to recover from but the amount of progress that's been made - and I really would appreciate any support that we get. This is a life-or-death story". "It is not a good news story when people are dying".
