During presidential campaigns, the candidates often talk about some of the things they promise to get done in their first 100 days in office if elected. That is the time frame that is the focus of this series hosted by Martha MacCallum. The first 100 days are even more important in 2017 with the presidency of Donald Trump, who may be the most unpredictable leader in American history. The show focuses on what is -- and is not -- getting done in the early stages of the Trump administration, the third administration to be covered by MacCallum since she joined Fox News in 2004.
