Tuesday, Febrary 4, 2020: Chaos caucus in Iowa

In what is supposed to be a defining day in the 2020 presidential campaign, we are left with an uncertain mess. The candidates, now in New Hampshire ahead of next week's primary, not knowing if they're winners or losers due to technical issues with the count. Iowa's Democratic party, holding a conference call with the campaigns this hour, says delayed caucus results should come later today. In the meantime, frustration, anger and plenty of spin from the candidates. And President Trump, hoping to look past impeachment and ahead to the 2020 election in tonight's State of the Union speech. Today's panel: Seung Min Kim and Rachael Bade with The Washington Post, Julie Pace with the Associate Press, and Julie Hirschfeld Davis with The New York Times. Also on the program: CNN's Leyla Santago and Jeff Zeleny.
