Donald Trump is attacking the Smithsonian and trying to whitewash the story of slavery. On The Oath and The Office, Corey Brettschneider and John Fugelsang explain why this is more than politics—it’s a constitutional fight over truth in American history. We also break down Trump’s unconstitutional order to abolish mail-in ballots, Congress’s role in election law, and Newsom v. Trump, where Judge Charles Breyer is weighing the Posse Comitatus Act and the Tenth Amendment.
