Former Facebook employee Frances Haugen, who testified in front of Congress last week that the tech company placed profits ahead of children’s safety, said on Monday that she has agreed to speak with the Facebook Oversight Board.

“I have accepted the invitation to brief the Facebook Oversight Board about what I learned while working there. Facebook has lied to the board repeatedly, and I am looking forward to sharing the truth with them,” Haugen tweeted.

Last week, Haugen testified in front of the Senate Subcommittee on Consumer Protection, Product Safety, and Data Security. She said Facebook was aware of how its products were harming children and teens, but still sought to profit off of their engagement, doubling down on targeting the younger demographic.
