Rodriguez said the campaign is aiming for a "strong top-three finish" in Iowa in order to give them a running start in other early contest states like New Hampshire.

The campaign also sent a memo to supporters on Thursday, laying out Harris's "path ahead" in the campaign. The memo said the campaign would add 60 more organizers in Iowa, as well as open 10 additional offices in the state.

Harris, who saw a surge in the polls and fundraising after the first debate in June, has since faded in a series of polls.

An NBC News-Wall Street Journal poll this week showed Harris’s support at 5 percent, down 8 points from the last survey conducted in July.

A tally conducted by FiveThirtyEight showed Harris spending considerably less time in the Hawkeye State than other candidates, including Biden.

The campaign's communications director, Lily Adams, said to expect to see Harris in the Hawkeye State every week.

“We’re planning to hit the gas here in October,” she said.
