SIOUX CITY (KTIV) - On Friday, former South Bend Indiana Mayor Pete Buttigieg was campaigning in Sioux City.



While speaking at the Orpheum Theatre, Buttigieg said that the next president will need a new way of thinking, to focus on issues of the future.

He said that he has set out from day one to have a different campaign, defined by belonging, and focused on unity.

In Iowa, Buttigieg remains locked in a close four-way race with Senators Elizabeth Warren, Bernie Sanders, and former vice president Joe Biden.

"The next president is going to face issues that are profoundly different than anything we've seen before. Climate change is upon us, the global security picture is changing, with everything from cyber attacks to health security issues like what we are seeing out of China. We are going to need to restore US credibility and deal with racial and economic equality here at home." said Pete Buttigieg.

With the caucus days away, this weekend will mark the candidates' final push to win over voters in Iowa.
