Comedian Stephen Colbert, the new host of CBS's "Late Show with Stephen Colbert," encountered hecklers in the September 10 airing of his new show while interviewing Uber CEO Travis Kalanick.

Eyewitnesses of the heckling told media outlets that multiple New York City cab drivers attending the show voiced their displeasure with the Uber ride-sharing service, arguing that it is robbing them on their jobs.

"When they initially started shouting, it was just loud and you couldn't really understand them," an eyewitness of the heckling told ET. "When Stephen looked up to listen to them, they calmed down a little bit and explained that they were angry that Uber is taking away jobs from cab drivers and is disrupting the New York City taxi system."

The eyewitness added to the media outlet that Colbert allowed the men to express themselves without motioning to security.

"Stephen just let the men speak and handled it himself," the eyewitness said. "He didn't motion for security or even look at anyone on his staff during the encounters."

Other eyewitnesses to the incident took to social media to share their experience.

"Two separate times during the interview with Uber guy, some cabbies in the balcony yelled stuff and interrupted the conversation," a social media user by the name of Sarah shared.

Colbert reportedly allowed the protesters to continue speaking before moving on with the interview, and later apologized to the audience, acknowledging that the existence of Uber was a "passionate" subject for all involved parties.
