Frances Haugen, a former Facebook employee, is set to testify Tuesday before Congress that the tech giant puts “profits before people” and that Congress should take action to regulate it. 

In written testimony released to reporters ahead of a Senate subcommittee hearing, Haugen — a former product manager on Facebook’s civic misinformation team — will say the social media company’s products “harm children, stoke division, weaken our democracy.”

“​​The company’s leadership knows ways to make Facebook and Instagram safer and won’t make the necessary changes because they have put their immense profits before people,” Haugen will testify. “Congressional action is needed.”
