Donald Trump received a warm welcome from Iowa State University students, signing autographed footballs.

He acknowledged the youth support, speaking to the Right Side Broadcasting Network, which backs his candidacy.

Trump then headed to a private stadium suite to watch Iowa's annual football rivalry with Iowa University.

His presence highlighted his dominant position in the Republican field in Iowa and nationally.

Florida Gov. Ron DeSantis attended the game with Iowa Gov. Kim Reynolds, seeking support.

Trump and DeSantis' rivalry was evident as they addressed different-sized crowds.

Despite some insults and protests, Trump's campaign remained active with volunteers and events.

Trump's infrequent Iowa visits contrasted with his campaign's organizational focus for the caucuses.
