The CEO of the ride-sharing company Uber offered a lengthy 13-part apology on Twitter on Tuesday as the company attempted to quell fallout over comments made by an executive who suggested targeting critical journalists.

Uber CEO Travis Kalanick apologized for comments made by Senior Vice President Emil Michael who, at a dinner over the weekend, floated the idea of hiring opposition researchers to dig up background information on journalists critical of the company.

The news, first reported by BuzzFeed, was much talked about Monday on social media. Michael issued an apology, saying "the remarks attributed to me at a private dinner — borne out of frustration during an informal debate over what I feel is sensationalistic media coverage of the company I am proud to work for — do not reflect my actual views and have no relation to the company’s views or approach. They were wrong no matter the circumstance and I regret them."
