President Barack Obama has added a stop in Sioux City to his Iowa travel plans this week.
Obama will hold an event Tuesday at Iowa State University in Ames, then will return to the state Saturday.
The Democrat had previously announced a visit Saturday to Des Moines, and on Monday a campaign official confirmed Obama has added the stop in Sioux City.
The events follow Obama's three-day bus tour of the state earlier in August.
Likely Republican presidential nominee Mitt Romney also has visited Iowa, including an event last week in Bettendorf.
Iowa is among seven states where neither candidate is believed to have a significant advantage, making the states key to deciding who will win the November election.
