It was a dark day that transfixed America and the world when a sea of Trump supporters stormed the Capitol on January 6th, 2021, hoping to overturn Joe Biden's election victory. Five people died in the melee. Now -- seventeen months later -- the much anticipated first public hearings of the committee investigating the insurrection have taken place.

While President Biden says that he won't abuse his executive power to enact gun restrictions, a bipartisan group of senators say they are making progress on bills designed to prevent gun deaths.

Now they've called for another march this Saturday. Cameron spoke to Christiane about whether he thinks there can be change.  Also on today's show: Actor Emma Thompson, antisemitism expert Deborah Lipstadt.
