"I understand the president's frustration in the sense that he has worked very hard to help Puerto Rico. that the effort to help them has been herculean", Francis said. "Then, a long time later, they started to report really large numbers, like 3,000".
The president argued the report puts the death tolls of 3,000 was done by Democrats to make him look bad.
Mr Trump said people who died for any reason - "like old age" - had been added to the total.
Trump bristled at criticism of his administration's handling of the Puerto Rico disaster as Hurricane Florence approached the coast of North Carolina with heavy rains that forecasters warned would cause catastrophic flooding across a wide swath of the US southeast.
Trump's tweets are not only disrespectful to the lives lost in Puerto Rico; they also assert a well-known trait of the president: no matter the tragedy, everything is always about him.
Santana's images appear to have been taken by drone, and he accompanied them saying, "Although you do not believe it ... nearly a million boxes of water that were never delivered to the people of PR, before the emergency of Hurricane Maria".

Florence becomes a hurricane; 2 other storms gain strength
Tropical storm force winds and some rain bands will likely begin Wednesday night, regardless of the actual landfall of the storm. Florence has been moving more toward the west and slightly northwest, potentially making direct landfall coming in from the east.
Researchers at the Milken Institute School of Public Health at George Washington University determined about 3,000 people died. "Ron DeSantis is committed to standing with the Puerto Rican community, especially after a tragic loss of life".
And House Speaker Paul Ryan, R-Wis., said, "I have no reason to dispute these numbers".
The death toll in Puerto Rico had been officially recorded as 64 for almost a year, despite convincing evidence that the figure was too low because official death certificates had failed to take into account the long-range impacts of the storm. Mr. Trump appeared confident that the federal response would be on par to his other "A pluses" in Texas and Florida, assuring those in the path of the storm: "We'll handle it, we're ready, we're able".
Trump visited the island on October 3, when the death toll was listed at 16, and he congratulated the island on avoiding "a real catastrophe like Katrina".
Florence was to be the first major test of FEMA since its response to the Puerto Rico disaster, which was widely criticised. "That is just what happened". "We are confident that the number - 2,975 - is the most accurate and unbiased estimate of excess mortality to date".
She says Trump's presidency is "the theater of the absurd every day".
