Trump said on Sunday American time that he did not want to see a second attack.
"We will investigate, but no, I wouldn't have wanted that, not a second attack. The first one was very deadly," he said, according to AFP.
The response comes after The Washington Post reported that a follow-up attack on a suspected drug boat on September 2 was carried out to kill survivors of the first.
The information, which has also been confirmed by sources including CNN , raises new questions about the legality of US operations in the Caribbean Sea.
The attack in question was the first in a series this fall against boats that the US government claims are transporting drugs to the United States.
Before the attack, Secretary of War Pete Hegseth had given a verbal order that everyone on board would be killed, two sources with insight into The Washington Post reported.
When the smoke cleared after the first hits, a live drone broadcast showed two survivors clinging to the wreckage. The commander in charge then ordered more missiles to be fired – to carry out Hegseth’s orders, according to the reports.
Hegseth has dismissed the information as "fake news" and Trump is still backing his Secretary of War.
"I'll find out, but Pete said he didn't order the men's deaths," Trump said.
