Last night, Facebook published two annotated slide decks in an attempt to contextualize the documents that the Wall Street Journal published this month, which reported evidence that the company is aware of its negative impact on teen mental health. These documents were released in anticipation of today’s Senate hearing on the mental health harms of Facebook and Instagram.

The Senate Committee on Commerce, Science, & Transportation questioned Facebook Global Head of Security Antigone Davis over two and a half hours, but lawmakers grew frustrated with Davis’ reticence to answer their questions directly, or provide much information that hasn’t been written in Facebook blog posts rebuking the WSJ reports.
