Facebook CEO Mark Zuckerberg told a joint hearing of the Senate Judiciary and Commerce committees on Tuesday that Facebook is working with special counsel Robert Mueller as part of his investigation into Russian interference in the 2016 presidential election.
“I know we are working with them,” Zuckerberg told Sen. Patrick Leahy (D-Vt.) during the hearing.
The social media mogul was hesitant to disclose information related to the probe because the work is “confidential,” but noted that some Facebook employees had been interviewed by the special counsel’s team.
Zuckerberg said he was not interviewed by Mueller.
“I want to be careful here, because our work with the special counsel is confidential and I want to make sure that in an open session I’m not revealing something that is confidential,” he said.

Leahy also asked whether or not Facebook had received a subpoena related to the investigation. Zuckerberg said they had been issued a subpoena before saying he was unsure.
“I have to clarify that I’m not sure that there are subpoenas. There may be,” he said.
Facebook has been under fire for its security and privacy policies since it was reported that political consulting firm Cambridge Analytica, which did work for the Trump campaign, illegally purchased access to the data of thousands of Facebook users.
Zuckerberg has vowed to improve privacy on the social media website and said it will hire 5,000 new employees to work on security and content review.
He will testify in front of the House Energy and Commerce Committee on Wednesday.
