A George Washington University study released last month estimated that 2,975 people died as a result of Hurricanes Irma and Maria.

In two tweets on Thursday, Trump said 3,000 people did not die as a result of Hurricanes Maria and Irma. He added that the revised death toll "was done by the Democrats in order to make me look as bad as possible when I was successfully raising Billions of Dollars to help rebuild Puerto Rico."

3000 people did not die in the two hurricanes that hit Puerto Rico. When I left the Island, AFTER the storm had hit, they had anywhere from 6 to 18 deaths. As time went by it did not go up by much. Then, a long time later, they started to report really large numbers, like 3000... — Donald J. Trump (@realDonaldTrump) September 13, 2018

.....This was done by the Democrats in order to make me look as bad as possible when I was successfully raising Billions of Dollars to help rebuild Puerto Rico. If a person died for any reason, like old age, just add them onto the list. Bad politics. I love Puerto Rico! — Donald J. Trump (@realDonaldTrump) September 13, 2018

The GW study reviewed mortality rates on the island on nondisaster years and compared them to rates post-Maria. According to the study, migration rates were also factored in to avoid miscounting the deaths, since tens of thousands of people left the island after the hurricanes.

The study was commissioned by the government of Puerto Rico shortly after the hurricane.

In his tweets, Trump quoted the official death count of 6 to 18 deaths during his October 2017 visit to the island.

"As time went by it did not go up by much," he added.

According to the study, in the six months after the hurricanes, 16,608 people died in Puerto Rico. Had the disaster not occurred, GW researchers estimate 13,633 people would have died in that same period.

In fact, the hurricane-related deaths peaked in January among the poorest residents of Puerto Rico, according to GW.
