Robert Costa's book 'Peril,' which he co-wrote with Bob Woodward, goes inside Trump's "war room" on the eve of the Jan. 6 insurrection. Costa reports on Trump's calls to his team, the tension between Pence and the president, and the ongoing threat to our democracy. The strategy of calling for an alternate slate of electors didn't work in January, but next election it might. "Imagine if in January 2025 Republicans are much more organized and they have alternate slates of electors ready in many states. What happens then?"
