Hurricane Maria made landfall in Puerto Rico on September 20, 2017 as a Category 4 storm.
If the new figures are accurate, Hurricane Maria is the deadliest storm to have hit Puerto Rico since the 1899 San Ciriaco hurricane.
It was an optimistic accounting of his administration's handling of the natural disaster, which left much of the U.S. territory without power for weeks and resulted in thousands of deaths.

One month after Maria, when the official number of people killed stood at 16, Trump said that the disaster was nothing compared to Hurricane Katrina's death toll.

The government's long-standing official death toll from Maria has been just 64 for the island territory which is part of the United States.
