Most of the top tier Democratic presidential candidates will be campaign in Iowa this weekend ahead of Monday's caucuses. But billionaire contender Michael Bloomberg will not be. Bloomberg campaign senior adviser Tim O'Brien joins the FOX News Rundown to discuss why the former New York City Mayor is banking on Super Tuesday instead.

He's had a long and incredible career on television, covering stories all around the world. FOX News correspondent-at-large, Geraldo Rivera is out with a new FOX Nation series called 'I Am Geraldo: 50 Years.' The veteran journalist tells us about his groundbreaking Willowbrook investigation, Al Capone's vault and what it's like being President Trump's friend.
