Trump tweeted after Cruz criticized the White House's response to Maria's disastrous impact on the U.S. commonwealth.
Directly responding to Trump's insulting tweets delivered from his New Jersey golf resort, Cruz dismissed the president out of hand, saying he was wrong about her and the people of Puerto Rico. "We'll worry about the big decisions later; that's the president's point".
Cruz, a member of the island's Popular Democratic Party, on Friday slammed Homeland Security Elaine Duke's comments that the administration's response to Puerto Rico, which was hit hard by Hurricane Irma and then devastated in a head-on hit by Hurricane Maria, as being a "good news story".
Tesla, Inc., is sending Puerto Rico hundreds of its Powerwall battery systems that can be paired with solar panels to help restore electric power to the island, according to a story from Bloomberg. Vital supplies like food and drinking water are stuck in ports and warehouses because of logistical breakdowns, almost half of the island is still in the dark and 90 percent of cell service is still down. "We have expanded greatly; probably 90 percent of the island is accessible now".
Several Puerto Ricans contacted by CNN stood up for San Juan Mayor Carmen Yulín Cruz, who apparently provoked the Trump tweet with a call for more aid, and many said the Puerto Rican community at home and overseas is already working together. She drew a sharp rebuke from the city's mayor for saying Thursday that the federal relief effort is "a good news story".
San Juan Mayor Carmen Yulin Cruz rejects that view and she's pressing Trump to "make sure somebody is in charge that is up to the task of saving lives". "I'm sorry but that really upsets me and frustrates me", said Cruz.More news: Jane Fonda snaps at Megyn Kelly on plastic surgery question
The mayor of San Juan is answering a Twitter attack by President Donald Trump by calling for a united focus on helping people in Puerto Rico after the US territory was devastated by Hurricane Maria. But you don't talk about the politics when people don't have enough food or water.
"They're waiting anxiously and will be very grateful to you and to the American people if you continue to step up to the moral imperative that you've taken on all over the world to help those in need".
"Puerto Rico was flattened ... but I'm here to help, I can tell you that", Trump said. And she heard him tell a crowd of businesspeople that Puerto Rico's government would have to help figure out how to pay the cost of the massive rebuilding effort.
But on Saturday, Federal Emergency Management Administration (FEMA) officials reported that a third of the island's telecommunications network had been restored, and some 765 gas stations - well over half - had fuel, though it was not clear how much.
"There's not a single trailer from FEMA or from response operations that are being held", said Alex de la Campa, the agency's Caribbean-area division director.
On Friday, the mayor of the Puerto Rican capital, Carmen Yulín Cruz, urged Trump to get the situation under control.
