Stephen Colbert has called the recent tweets by Donald Trump “sickening” as the U.S. president denied the reported number of deaths caused by last year’s hurricane in Puerto Rico.

“I just wanna state that not only is this a sickening tweet, it is in no way true,” Colbert said in his opening monologue on Thursday’s edition of “The Late Show”.

Colbert was referring to tweets Trump made on Thursday disputing the reported death toll in Puerto Rico after Hurricane Maria:

Trump claimed the numbers were boosted “by the Democrats” in an effort to make him “look as bad as possible”:

As the late-night host pointed out, Puerto Rican officials had asked researchers at George Washington University’s Milken Institute School of Public Health to conduct a study into the deaths, the results of which found that an estimated 2,975 died as a result of the disaster.

Colbert stated that the report “had been pushed out of the front pages because of all the other bad news about Donald Trump.”

“It’s kinda like he was on trial for littering, and he said on the stand, ‘I only threw that cup out of my window because I was distracted by the homeless man I ran over. Pretty sure he died of old age.'”
