Uber has faced many protests over its ride-hailing app, but this time the protests came directly to the CEO.

During a taping of "The Late Show with Stephen Colbert," Uber's CEO, Travis Kalanick, was interrupted by at least one protester in the upper balcony, according to several Business Insider reporters who were there and witnessed it.

The first time, the protester stood up during the taping and accused Kalanick of destroying taxi-industry jobs. Colbert let the protester speak for awhile, before saying that he had a question about that in his cue cards anyway.

Kalanick maintained that Uber pays better and offers more flexible hours than the taxi industry, an oft-repeated stance by the company.

Later, after Colbert did ask about "disruption" and potential negatives to Uber's business model, someone started yelling again and claimed that everything Kalanick was saying was a lie.

Colbert apologized for his audience in the end, saying that there was a lot of "passion" around the issue in New York City. Because an emotional interview with US Vice President Joe Biden ran long, it's unclear if the interview with Kalanick will run tonight as scheduled.

Business Insider reached out to Uber and CBS and will update this story if we hear back.
