Facebook CEO Mark Zuckerberg seemed to reverse his company's stance on whether it played a role in the riot at the U.S. Capitol in January.

In response to questions from Rep. Jan Schakowsky (D., Ill.), Mr. Zuckerberg said that the presence on Facebook of content related to the riot showed the company has work to do.

"I'm sorry to interrupt...but would you admit that Facebook played a role?" Rep. Schakowsky said.

"Certainly there was content on our services," Mr. Zuckerberg responded.

In January, Facebook Chief Operating Office Sheryl Sandberg said the siege was planned on smaller social networks, and not on Facebook.
