"He continued:" ... The fact is that Puerto Rico has been destroyed by two hurricanes.
Trump is scheduled to visit Puerto Rico on Tuesday along with First Lady Melania Trump.
Carmen Yulin Cruz, the mayor of Puerto Rico's capital city, San Juan, had accused the Trump administration of failing the U.S. territory.
On Friday, Mayor Carmen Yulín Cruz voiced dissatisfaction over the United States' response to Maria, which knocked out power to most of the island and has many scrambling for food, water, and shelter.
President Donald Trump responded to Cruz's rebuke, saying the mayor "has now been told by the Democrats that you must be nasty to Trump".
The "politically motivated ingrate" he's referring to is nearly certainly Cruz, as it fits the pattern of POTUS's tweets from Saturday, when he lashed out at the San Juan mayor and the people of Puerto Rico who "want everything to be done for them".
Trump said, "All appropriate parts of our government from Homeland Security to Defense are engaged fully in the response and the recovery effort probably has never been seen for something like this. Fantastic job!" Trump tweeted, excluding Cruz from his praise.
"I know the good heart of the American people and I know that when a mayday sound goes off, they come to the rescue, " she said on ABC's "This Week".
"The ones we hear from, all we're hearing is they are starving, thirsty".
"Foreign flag ships are typically not allowed in to deliver these products unless USA carriers can't do it, and the administration's view was they got all the commodities in to Puerto Rico, they didn't need to waive the Jones Act".
The president's criticism of the San Juan mayor drew a strong response from some on Twitter, including famed "Hamilton" creator, Lin-Manuel Miranda. People on the side of the road were standing near cell towers just to see if they can get reception.
"The electrical grid and other infrastructure were already in very, very poor shape, they were at their life's end prior to the hurricanes, and now virtually everything has been wiped out", Trump said. She told ABC News that since the storm hit, they had been surviving by using water from the creek behind the nursing home, and getting drinking water from her father's well. "We don't know if they're alive or not", Espada said, an event coordinator.
"I have been patient", she said Friday afternoon (video below). It is unclear if he was praising first responders again or others in the USA territory.
He added: "We're going to have to, essentially, rebuild this island".
