Guest: Travis View, Co-host, “QAnon Anonymous” Podcast

Facebook removed hundreds of accounts related to the far-right conspiracy theory QAnon last week, following the example of other social media platforms.

Good news: new research shows that crackdowns on toxic chemicals in the last couple decades are paying off. Childhood brain damage numbers are down.
