"Trump and DeSantis Clash in Iowa as Caucuses Loom"

Former President Donald Trump and Florida Gov. Ron DeSantis head to Iowa for campaign events with different objectives. Trump, leading in the polls, plans to focus on criticizing President Joe Biden and potentially looking towards a general election rematch. DeSantis, lagging behind in the race, aims to gain momentum and close the gap between him and Trump. Trump's campaign launches TV ads in Iowa targeting Biden, while DeSantis seeks to capitalize on endorsements from Iowa Gov. Kim Reynolds and evangelical leader Bob Vander Plaats. Nikki Haley, who has seen a rise in polling, receives an endorsement from a conservative political advocacy group. Trump is skipping the upcoming Republican debate in Alabama but will participate in a town hall in Iowa.
