Microsoft announced that it is endorsing bipartisan legislation intended to hold Big Tech companies accountable for ensuring that teenagers and children are safe online.

Microsoft Vice Chairman and President Brad Smith released a statement on Tuesday endorsing the Kids Online Safety Act, a bill co-sponsored by Sens. Richard Blumenthal (D-IL) and Marsha Blackburn (R-TN). KOSA would require social media companies to implement controls for users, including options for limiting screen time, restricting addictive features, and limiting access to user profiles. The legislation was approved by the Commerce Committee in July and is awaiting a floor vote. Microsoft is the second major technology company to speak out in support of KOSA.
