Instagram CEO Adam Mosseri will testify before Congress for the first time about how the social media app is trying to keep young people safe, amid criticism that the photo and video service is harming the mental health of teens.

“These are important issues, but we have shared goals. We all want young people to be safe when they’re online,” Mosseri, who has three children, said in a video posted on Twitter last week.

The Senate Commerce, Science and Transportation Subcommittee on Consumer Protection, Product Safety and Data Security will hold the hearing on Dec. 8, at 2:30 p.m. ET. The hearing, titled Protecting Kids Online: Instagram and Reforms for Young Users, will look into “bombshell reports about Instagram’s toxic impacts,” Sen. Richard Blumenthal said Wednesday.

Sen. Blumenthal, a Democrat from Connecticut, has been hosting a series of bipartisan hearings about child safety along with Senator Marsha Blackburn and others.
