The University of Iowa's website says that the Democratic candidate for Senate from New Jersey will be giving a lecture on the Iowa City campus on Aug. 29. But Booker campaign spokesman Kevin Griffis says Monday that Booker will not give the speech.

Griffis says the speech was scheduled before the special Senate election was called in New Jersey. He says they had since cancelled the event, but there had been some kind of miscommunication.

The potential of a Booker visit to Iowa drew attention because of the state's presidential caucuses, which prompt speculation about politicians who schedule events in Iowa.
