BRANCHBURG, N.J. (AP) -- President Donald Trump on Sunday scoffed at "politically motivated ingrates" who had questioned his administration's commitment to revive Puerto Rico after a pulverizing hurricane and said the federal government had done "a great job with the almost impossible situation."
The tweets coming from a president ensconced in his New Jersey golf club sought to defend Washington's efforts to mobilize and coordinate recovery efforts on a U.S. territory in dire straits almost two weeks after Hurricane Maria struck.
San Juan Mayor Carmen Yulin Cruz on Friday accused the Trump administration of "killing us with the inefficiency" after the storm. She begged the president, who is set to visit Puerto Rico on Tuesday, to "make sure somebody is in charge that is up to the task of saving lives," and appealed for help "to save us from dying."
She explained in a television interview Sunday that "there's only one goal, and it's saving lives," adding that all she did "was ask for help."
Trump's weekend tweets have shown him to be contemptuous of their complaints of a laggard U.S. response to the natural disaster that has imperiled the island's future.
"We have done a great job with the almost impossible situation in Puerto Rico. Outside of the Fake News or politically motivated ingrates," he tweeted on Sunday.
He said "people are now starting to recognize the amazing work" done by the Federal Emergency Management Agency and the military.
And Cruz told "This Week" on ABC: ""I know the good heart of the American people and I know that when a mayday sound goes off, they come to the rescue."
The day before, Trump had tweeted: "Such poor leadership ability by the Mayor of San Juan, and others in Puerto Rico, who are not able to get their workers to help."
He added: "They want everything to be done for them when it should be a community effort," Trump wrote from his club.
His critical response was an unusually pointed rebuke from the president in the heat of a disaster — a time when leaders often put aside partisan differences in the name of solidarity. But it was a reminder of Trump's unrelenting penchant for punching back against critics, whatever the circumstances.
Trump has said he's doing everything possible to help the "great people of PR!" and has pledged to spare no effort to help the island recover from Maria's ruinous aftermath. He has also repeatedly applauded his government's recovery efforts, saying military personnel and first responders have done "an amazing job," despite the significant logistical challenges.
Thousands more Puerto Ricans have received water and rationed food as an aid bottleneck has begun to ease. But many, especially outside the capital, remain desperate for necessities, including water, power and fuel.
Trump's administration has tried in recent days to combat the perception that he failed to quickly grasp the magnitude of Maria's destruction and has given the U.S. commonwealth less attention than he'd bestowed on states like Texas, Louisiana and Florida after they were hit by hurricanes Harvey and Irma. Trump had repeatedly praised the residents of those states as strong and resilient, saying at one point that Texas could "handle anything."
Administration officials have held numerous press conferences providing updates on relief efforts and Trump on Saturday spoke by phone from New Jersey with FEMA Administrator Brock Long, Puerto Rico's governor, Ricardo Rosselló, and other several other local officials.
But after a week of growing criticism, the president's patience appears to be waning.
"The Mayor of San Juan, who was very complimentary only a few days ago, has now been told by the Democrats that you must be nasty to Trump," the president charged, without substantiation.
Long added: "The problem that we have with the mayor unfortunately is that unity of command is ultimately what's needed to be successful in this response," he said, requesting that she report to a joint field office.
Cruz declined to engage in the tit for tat, instead calling for a united focus on the people who need help. "The goal is one: saving lives. This is the time to show our 'true colors.' We cannot be distracted by anything else," she tweeted, along with photos of herself meeting with residents and rescue workers, wading hip-deep through a flooded street and comforting an elderly woman.
After a day of tweets criticizing the news media, Trump seemed to echo the sentiment: "We must all be united in offering assistance to everyone suffering in Puerto Rico and elsewhere in the wake of this terrible disaster."
Trump's Saturday tweets are the latest example of his insistence on "punching back," even against those with far less power. After a deadly terror attack in London in June, for instance, Trump singled out London Mayor Sadiq Khan, suggesting he wasn't taking the attacks seriously enough.
Natural disasters sometimes bring moments of rare bipartisan solidarity. In the aftermath of Superstorm Sandy, which wreaked havoc along the East Coast in 2012, New Jersey's Republican governor, Chris Christie, praised Democratic President Barack Obama for his personal attention and compassion at a joint press conference. Still, the fight over relief money became politicized and contentious, with numerous Republicans voting against a delayed relief bill.
In the aftermath of Hurricane Katrina and Hurricane Andrew, tensions between local and federal officials also ran high. Then-New Orleans Mayor Ray Nagin pleaded with the government to send help in sometimes colorful terms, while Terry Ebbert, the city's Homeland Security director, called relief efforts a "national disgrace."
