An advocacy group flooded the front lawn of the Capitol building with cutouts of Facebook CEO Mark Zuckerberg ahead of the tech leader’s congressional testimony Tuesday.

The group, Avaaz, identifies as a global advocacy group focused on national and regional issues and placed 100 life-sized cutouts of Zuckerberg with a T-shirt that said “fix fakebook,” on Capitol Hill to call on the Facebook CEO to adopt several company changes.

The group is calling on Zuckerberg to “ban all bots, alert the public any and every time users see fake or disinformation, fund fact checkers around the world, and submit to an independent audit to review the scale and scope of fake news,” according to a press release.



The stunt comes as Zuckerberg is set to testify before a joint Senate hearing to take questions regarding the company’s handling of user data.

Controversy erupted last month when news surfaced that Facebook shared information on more than 50 million user accounts with the data firm that worked with the Trump campaign, Cambridge Analytica, ahead of the 2016 presidential election. Last week, it was revealed that as many as 87 million people were impacted.
