And like his earlier travels, it had its peculiar moments: He also gently tossed rolls of paper towels into a crowd that gathered to see him at Calvary Chapel, outside the islandâs capital, San Juan.
This time, however, Mr. Trump flew into a different kind of turbulence. Over the weekend, the president lashed out at the mayor of San Juan, Carmen YulÃn Cruz, after she complained that the federal response in Puerto Rico had fallen short of the responses in Texas and Florida. She was not mollified after meeting him.
âThe first part of the meeting was a public-relations situation,â Ms. Cruz said in an interview with CNN about the briefing she attended with the president. While she said the White House staff was helpful and receptive, Mr. Trumpâs communications style sometimes âgets in the way.â
âI would hope that the president of the United States stops spouting out comments that really hurt the people of Puerto Rico,â she said, âbecause, rather than commander in chief, he sort of becomes miscommunicator in chief.â
Mr. Trump greeted the mayor but did not invite her to speak, recognizing instead Mr. RossellÃ³, whom the president said âdid not play politics,â and its congressional representative, who lavishly applauded the administrationâs performance.
âThank you, Mr. President, for all you have been doing for the island,â said Jenniffer GonzÃ¡lez-ColÃ³n, the territoryâs nonvoting representative, who declared that Washington had sent everything Puerto Rico needed.
âYou were really generous,â Mr. Trump replied. âItâs so important when you have men and women that have worked so hard and so long, and many of them came from two other catastrophic hurricanes.â
The president then went around the briefing table, praising the director of the Federal Emergency Management Agency, military commanders and a half-dozen members of his cabinet who accompanied him to Puerto Rico â which was already facing about $74 billion in debt even before the hurricane hit.
In singling out Mick Mulvaney, his budget director, Mr. Trump said, âI hate to tell you, Puerto Rico, but youâve thrown our budget a little out of whack.â Looking around the room for his chief of staff, John F. Kelly, who was standing in the back, Mr. Trump said, âBoy, is he watching.â
Before leaving the White House on Tuesday, Mr. Trump told reporters he believed Ms. Cruz was now mostly satisfied.
âI think sheâs come back a long way,â he said. âI think itâs now acknowledged what a great job weâve done.â He asserted that the relief effort was as effective as those in Texas and Florida, and he added, âItâs actually a much tougher situation.â
Mr. Trump, however, repeated his earlier criticism that some Puerto Ricans were not doing enough to help themselves. Despite the roads being cleared and communications being re-established, he said, truck drivers were not transporting enough supplies. âWe need their truck drivers to start driving trucks,â he said. âOn a local level, they have to give us more help.â
On Saturday, after Ms. Cruz angrily disputed the administrationâs assertion that the relief effort was going well, the president fired back in a Twitter post that she had been instructed by Democrats to be ânasty to Trump,â and added that Puerto Ricans âwant everything to be done for them.â
White House officials were nervous that Mr. Trump would be set off again if he were greeted by protesters in Puerto Rico. As late as Monday afternoon, some aides were urging the president to delay the visit, which came a day before he was scheduled to fly to Las Vegas to meet with law enforcement officials and victims of Sundayâs mass shooting there.
There were a few other signs of discontent on Tuesday. As Mr. Trumpâs motorcade drove from an air base to a church â passing hundreds of downed trees â it also passed a woman clutching a placard that said, âYou are a bad hombre,â according to a pool report.
Sitting in a traffic jam near the San Juan airport before the arrival of Air Force One, a resident, Jaime Vega, disputed Mr. Trumpâs claim that Puerto Ricans should be doing more to help their own recovery. âWe are doing,â he said. âItâs only now that they are doing something.â
âLet him come so he can see what there really is, and so nobody can tell him made-up stories,â said Mr. Vega, an accountant.
Outside a bar in the Santurce neighborhood of San Juan, an hour after Air Force One departed Tuesday afternoon, people debated what Mr. Trumpâs visit might have accomplished.
âHe was just measuring Puerto Rico by the amount of dead compared to Katrina,â said JosÃ© Tormos, 62, an employee of the local government in Guaynabo. âFEMAâs response has been too slow.â
Even before the death toll was increased on Tuesday evening, others noted that the actual number of people killed by Hurricane Maria may rise significantly, given that the earlier, certified tally was outdated and that the island governmentâs record-keeping ability has been damaged by the storm. Mr. RossellÃ³ said 19 of the total 34 deaths so far were directly related to the storm, like drownings. The others included electrical failures of oxygen tanks, suicides and natural causes like heart attacks, he said.
Marlene Martinez, 51, an accountant, said, âItâs just an example of how weâre treated like second-class citizens.â
Others were more concerned about the reconstruction of the island and their own precarious situations than Mr. Trumpâs comments.
âThe people of Puerto Rico donât care whether Trump is the god or the devil,â said Edgardo Tormos, 58. âThis is about the recovery of Puerto Rico.â
Still, others seemed happy just to have the president in their midst. In a 20-minute visit to Calvary Chapel, an English-speaking evangelical church that has become a collection center for supplies, Mr. Trump shook hands, took selfies and offered encouragement in the chapelâs sanctuary.
âFor us, itâs really nothing political,â said Naitsa Marrero, an administrative assistant who helped organize the stop. âPuerto Rico needs help, and often this type of thing sheds light on whatâs happening here â a crisis.â
Jason Dennett, the churchâs pastor, said he welcomed the idea of a visit when the Secret Service contacted him five days ago. âHe offered his help to the people of Puerto Rico,â Mr. Dennett said. âHe said he was here to help and that the support would continue.â
Mr. Trump boarded a Navy amphibious assault ship for meetings with the governors of Puerto Rico and the United States Virgin Islands. The White House asked the Virgin Islandsâs governor, Kenneth E. Mapp, to fly to Puerto Rico because of the logistical complications of flying the president to those islands, parts of which have been severely damaged.
Still, Mr. Mapp told him, âbecause of your commitment, Mr. President, weâre talking about opening schools and welcoming cruise ships back.â
Mr. Trump has gotten used to being a kind of second responder, having traveled to Texas and Florida after two other hurricanes over the past two months. Since the weekend, Mr. Trump has sharply scaled back his Twitter posts about the hurricanes or other potentially charged issues.
But speaking to reporters on Tuesday, he continued to emphasize the governmentâs performance rather than the plight of the victims.
âIn Texas and in Florida, we get an A-plus,â Mr. Trump said. âAnd Iâll tell you what, I think weâve done just as good in Puerto Rico.â
