Both vice presidential candidates will spend their afternoon in Iowa, with Democrat Joe Biden in Burlington and Republican Paul Ryan in Des Moines.
Biden will speak Monday afternoon at the Port of Burlington in the Mississippi River town as he begins a two-day trip to Iowa. He'll hold events Tuesday in Ottumwa and Grinnell.
Ryan will hold a Monday afternoon event at a downtown Des Moines hotel. That's a change from earlier plans to hold an outdoor rally at the downtown Simon Estes Amphitheater.
The stops continue a string of visits to Iowa by the presidential and vice presidential candidates.
Iowa is one of about six battleground states that likely will decide whether Democratic President Barack Obama or Republican challenger Mitt Romney wins the Nov. 6 presidential election.
