Washington: Facebook is not doing enough to safeguard children on its Messenger Kids app and their privacy is at risk, US Democratic Senators have stressed. Responding to Facebook's reply to their earlier letter, Senators Ed Markey (D-MA) and Richard Blumenthal (D-CT) said that Facebook has to do a lot better to protect kids on its Messenger Kids platform, The Verge reported on Wednesday.

"Facebook's response gives little reassurance to parents that Messenger Kids is a safe place for children today," the Senators said. "We are particularly disappointed that Facebook did not commit to undertaking a comprehensive review of Messenger Kids to identify additional bugs or privacy issues," they added.
