In Florida, which was badly hit by Hurricane Irma previous year and which received thousands of Puerto Ricans fleeing the devastation of their homes, Republican gubernatorial candidate Ron DeSantis - who has built his campaign around his adherence to Trump's politics - tried to distance himself from the president's words.
And just Thursday, Trump accused Puerto Rican officials and Democrats of lying about how many people died there in a coordinated effort to make him look bad after Hurricanes Maria and Irma pummeled the US island territory.
Puerto Rico Governor Ricardo Rossello commissioned George Washington University's Public Health School to look into the question. Researchers used what they called a "state-of-the-art mathematical model", which Trump misrepresented - wrongly saying the study counted deaths "for any reason, like old age".
Maria devastated the island in September 2017 and knocked out the entire electricity grid.
Trump's remarks were criticized by lawmakers on both sides of the aisle, including some of the his strongest supporters, such as Florida Republican gubernatorial candidate Ron DeSantis and current Florida governor and Senate candidate Rick Scott.
"3000 people did not die in the two hurricanes that hit Puerto Rico". Trump tweeted that the reported number of about 3,000 was inaccurate and had been pushed by opponents just to make him look bad.
"President Trump was responding to the liberal media and the San Juan mayor who sadly have tried to exploit the devastation by pushing out a constant stream of misinformation and false accusations", White House spokesman Hogan Gidley said in a statement.
Trump on Thursday morning tweeted he believed between six and 18 people died as a result of the storm that struck the island as a Category 4 hurricane.
After Trump blamed democrats for reporting a higher death toll from the September 2017 storm, Cora said he doesn't think the matter should be viewed as a political issue.
Trump followed up his first Thursday tweet by blaming Democrats - without evidence - for raising the death toll. Sober as the New York Times is in reporting Trump's latest big lie, it still represents in characterizing him how low we've sunk.
On Wednesday, Puerto Rican officials said about 20,000 pallets of water bottles shipped to Puerto Rico after Maria went unused and became too contaminated to drink.
George Washington University said in a statement that it stands by its study.
FEMA officials confirmed that the agency's efforts to deploy more resources early are intentional, noting that increased pre-storm preparation were among the agency's recommendations in its assessment of its performance during hurricane season past year.
As the days went by, the death toll kept increasing, eventually reaching 64. He declined to comment even after reporters described what Trump wrote.
