Protesters also held up signs that said "Stop Corporate Spying" amid cardboard cutouts of Zuckerberg's face.

A person wearing a blue and green pointy wig, aiming to look like a Russian troll, watched from the back of the room as the Senate kicked off its hearing with Facebook CEO Mark Zuckerberg. The person wore a red and blue Russian flag around his neck.

Other protesters held up signs that said "Stop Corporate Spying."

Judiciary Committee Chairman Chuck Grassley noted that the crowd was not big by the standards of the gargantuan social network platform. But the hearing room was filled, with a line of hundreds of people waiting down the hall and into the next office building.

Zuckerberg is testifying in the Senate on Tuesday and the House on Wednesday. He agreed to testify after revelations that Cambridge Analytica, a data-mining firm affiliated with Donald Trump's presidential campaign, gathered personal information from 87 million users to try to influence elections.

Senators are expected to also ask him about Russian interference on his company's platform in the 2016 election.

In testimony released Monday, Zuckerberg apologizes for the privacy scandal and for not recognizing Russian interference sooner.
