Earlier this month a mostly white mob raided the Capitol, vandalizing the building, threatening to kill members of Congress and then-Vice President Mike Pence, and attacking police officers, killing one.

The deadly attack was driven not just by Donald Trump’s lies about a stolen election but by years' worth of misinformation, conspiracy theories, and the increase of white supremacist organizing and radicalization online.

Rick and Dawn Collins understand white supremacist violence all too well. Their son, Army 1st Lt. Richard Collins III, was a Black Bowie State University student murdered in a racist attack just three days short of graduation in 2017.

The Collinses join us to share their perspectives.

Plus, we talk to Angelo Carusone, President of Media Matters, about the role that social media played in the Capitol attack and what social media companies are--or aren't--doing to push back against white supremacy and conspiracy theories online.
