The campaign for President Barack Obama has released more details about Vice President Joe Biden’s trip to Iowa next week, noting he will hold events in Ottumwa and Grinnell.

Biden will arrive in Iowa on Monday and hold an event at the Port of Burlington.

On Tuesday, he will speak at The Bridge View Center in Ottumwa, then later in the day will speak at Grinnell College.

The events are free and open to the public, but tickets are required.

Biden’s stops continue a string of visits to Iowa by the president and vice president, as well as Republican nominee Mitt Romney and his running mate Rep. Paul Ryan.

Iowa is one of about six battleground states that likely will decide the winner of the presidential election.
