Trump made the slip-up while addressing the Values Voter Summit in Washington, D.C., becoming the first sitting president to appear at the anti-LGBTQ event.
"We are one nation and we all hurt together, we hope together and we heal together", he said, later adding, "The Virgin Islands and the President of the Virgin Islands, these are people that are incredible people, they suffered gravely and we're be there, we're going to be there, we have really, it is not even a question of a choice".
The White House later released an official transcript of the speech, striking out Trump's reference to the Virgin Islands' "president" and noting he was referring to its "governor".
After saying that Puerto Rico was "a country that already had its challenges before this storm", Perry was interrupted by Rep Kathy Castor who told him "It's America".
Trump is the president of the U.S. Virgin Islands. The Virgin Islands were hit by both Hurricanes Irma and Maria 12 days apart.
The islands are a United States territory-so Trump is the president. According to NBC, officials have calculated the economic losses to Virgin Islands at more than $2 billion.
Trump isn't the first person in his administration to make this mistake.
Perry then apologized. Earlier in the hearing, he correctly referred to Puerto Rico as a territory.
It's not really any wonder that 52% of people feel that Trump "doesn't care about the problems facing Puerto Rico after Hurricane Maria".
