US President Donald Trump will fly to Puerto Rico on Tuesday to survey the destruction caused by Hurricane Maria in a show of solidarity with survivors amid criticism that the government was slow to respond to the disaster two weeks after it struck. The president is expected to spend more than five hours on the island, meeting with first responders, local officials and some of the residents struggling to recover from a hurricane that, in Trumps words, left the island US territory "flattened." The trip will be Trumps fourth to a region battered by storms during an unusually violent hurricane season that has also seen parts of Texas, Florida, Louisiana and the US Virgin Islands inundated by floodwaters and whipped by winds. The trip gives Trump the chance to demonstrate how his government intends to help them recover after they were hit by the worst hurricane in 90 years. The economy of the US territory, home to 3.4 million people, was already in recession. Its government filed for bankruptcy in May. The storm wiped out the power grid, and less than half of residents have running water. Two weeks on, it is still difficult for residents to get a cell phone signal or find fuel for their generators or cars. About 88 percent of the cellphone sites are still out of service. Valentine Navarro, 26, a salesman in San Juan, shrugged off Trump’s trip as a public relations exercise. “I think he’s coming here because of pressure, as a photo-op, but I don’t think he’s going to help more than he has already done – and that’s not much,” Navarro said. Trump got high marks for his handling of Hurricane Harvey in Texas and Hurricane Irma in Florida and the Caribbean. Caught off guard by the severity of Hurricane Maria’s damage to the US island territory, Trump did not focus on the storm for days, instead launching a barrage of tweets over his view that National Football League players should be required to stand during the US national anthem. A previous Republican president, George W. Bush, faced widespread criticism for his administration’s initial handling of Hurricane Katrina, which killed some 1,800 people in and around New Orleans in 2005. Images of Trump standing together with mayors, the governor and federal officials would go a long way toward showing Americans the White House is addressing the hurricane damage, said retired Coast Guard Admiral Thad Allen. Allen, who led the federal response to Hurricane Katrina and the Gulf oil spill, said the presidential visit will provide the chance to communicate that Americans care about the disaster on the isolated island territory. But he warned against rhetoric that downplayed the challenges ahead or overstated accomplishments. “Piling superlatives on work that is yet to be completed is not helpful,” Allen said in an interview. “What you need is transparent, credible, open communication with the American people.” Trump should offer specifics to Puerto Ricans about the path forward to give people hope so they can begin planning how to rebuild, said Lars Anderson, who was a senior Federal Emergency Management Agency official in Democratic President Barack Obama’s administration. “He needs to talk about what exactly does his administration plan to do: how are they going to rebuild Puerto Rico? How are they going to deal with the fact that there are parts of Puerto Rico that aren’t going to get power for six months?” said Anderson, who now runs a crisis communications firm called BlueDot Strategies. Trump’s administration has so transferred more than $20.5 million in federal funds to the territory to help defray disaster expenses, the Federal Emergency Management Agency said on its website. The administration is preparing to ask Congress for $13 billion in aid for Puerto Rico and other areas hit by natural disasters, according to congressional sources said. But that money will only go so far. The island’s recovery will likely cost more than $30 billion. Even before the storm hit on September 20, Puerto Rico was in dire condition thanks to a decade-long economic recession that had left its infrastructure, including the islands power lines, in a sorry state. On Monday, the nonprofit Oxfam announced that it would be taking the rare step of intervening in an American disaster, citing its outrage over what it called a "slow and inadequate response."
