In addition to obstruction of justice, prosecutors charged Sullivan with failing to share knowledge of a felony. In total, he faces up to eight years in prison if convicted of both charges. 

“We expect good corporate citizenship,” said US Attorney David L. Anderson. “We expect prompt reporting of criminal conduct. We expect cooperation with our investigations. We will not tolerate corporate cover-ups. We will not tolerate illegal hush-money payments.” 

Bradford Williams, Sullivan’s attorney, told The New York Times there’s “no merit” to the charges. “If not for Mr. Sullivan’s and his team’s efforts, it’s likely that the individuals responsible for this incident never would have been identified at all,” he said. Williams added that Sullivan and his team worked closely with other Uber employees and followed the company’s policies.

Meanwhile, a spokesperson for Uber told The New York Times it continues to cooperate with the Justice Department’s investigation into the 2016 hack. “Our decision in 2017 to disclose the incident was not only the right thing to do, it embodies the principles by which we are running our business today: transparency, integrity, and accountability,” they said.

Sullivan may become the second former Uber employee to end up behind bars. At the start of August, Anthony Levandowski, the engineer at the center of the trade secret legal battle between Waymo and Uber, was sentenced to 18 months in prison.
