With the Iowa caucuses less than a week away, all the polls are showing one clear message: former President Donald Trump remains the Republican frontrunner. In the face of unprecedented legal troubles and mounting lawsuits, the former president’s campaign has thrived as he speaks out against these cases, which he calls election interference. Trump will join Martha MacCallum, anchor and executive editor of The Story, and Bret Baier, FOX's chief political anchor, on Wednesday for a town hall to discuss his presidential campaign.
