The Des Moines Register-sponsored poll had shown Harris leading Trump by three points in the reliably red state.
However, a poll released later in the day by Emerson College showed that Trump had a 10-point lead, 53% to 43%.
The Trump campaign responded to the Des Moines Register poll by calling it a “clear outlier.”
“Des Moines Register is a clear outlier poll. Emerson College, released today, far more closely reflects the state of the actual Iowa electorate and does so with far more transparency in their methodology,” the campaign said.
