Saleh said in the video that one passenger told him to "shut the f- up", and he addressed others who apparently claimed they were "uncomfortable".
The Daily Dot has reached out to Saleh about the incident, but so far has not received a response.
He also said that it was "six white people against us bearded men".
In the footage, Saleh claims they were being removed from the plane because other passengers complained he was speaking Arabic.
"We take all allegations of discrimination seriously and we are gathering all of the facts before jumping to any conclusion", a statement said.
Many are taking that response, which was sent to other journalists, to mean Delta favored prejudiced passengers over the victims. He later remarked that he speaks to his mother before every flight and she does not speak English.
Some have called the legitimacy of Saleh's posts into question since he's been known to post prank videos, including pranks involving air travel, on YouTube.
In the video tweeted by Adam shows he and his friend were about to be removed from the flight at Heathrow airport. Earlier this year, an Ivy League economist was removed from an American Airlines flight after his neighboring passenger noticed him drawing unfamiliar symbols next to her. Turns out he was just doing math equations. He later said the incident didn't happen. "I spoke a word in a different language and you guys feel uncomfortable?" he continued.
Saleh told his 275,000 Twitter followers to #BoycottDelta because he got the boot from a plane to New York City.
"We're getting kicked off the plane because we spoke a different language", the YouTube prankster says directly into the camera at one point. "They were not arrested and no offences were disclosed", the police said in a statement.
