The Democrat is expected to campaign on Oct. 22-23 in Des Moines and Cedar Rapids in the first-in-the-nation caucus state, with other events likely to be added, Politico reported.

Harris's trip will come after her visit to South Carolina, an early-voting state and the first Southern state to hold a primary during the primary season.

Harris has raised more than $5 million this year for party candidates and said recently that she would "take a look" at a possible 2020 presidential run following November's midterm elections.

Harris's office did not immediately respond to The Hill's request for confirmation of the campaign stop.

Other possible 2020 contenders are already making their way to the Hawkeye State.
