RFK Jr. urged IA-03 Libertarian Marco Battaglia to leave race
Sponsor: Robert F. Kennedy Jr. / White House-linked political outreach; later subject of Sen. Ron Wyden Hatch Act complaint · Date: June 8 / July 14, 2026
Former IA-03 Libertarian candidate Marco Battaglia told AP and The Washington Post that Kennedy called him June 8 and encouraged him to drop out of the competitive race, warning about Democratic control of the House. Wyden later included that call in his Hatch Act complaint. This matters to the Nunn race because the outreach was intended to reduce third-party competition, but it is not evidence by itself that Zach Nunn’s campaign directed Kennedy.
IA Fact Check assessment: Kennedy outreach reported; Nunn-campaign coordination not established; Hatch Act allegation unresolved
Battaglia’s account of Kennedy’s call is independently reported, although unlike Stewart’s IA-02 call, Battaglia said he did not record it. The Washington Post reported that both Libertarians had unexpected outreach from their Republican counterparts before Kennedy contacted them, but the available record does not establish that Nunn’s campaign asked Kennedy to intervene or coordinated the call. Wyden’s complaint alleges unlawful conduct by Kennedy and asks OSC to investigate; it is not a final finding. Battaglia was later removed from the ballot in a separate state objection proceeding, which should not be conflated with Kennedy’s call.
Pete Hegseth campaigns for Nunn at the Iowa State Fair
Source: Pete Hegseth / Zach Nunn campaign event; independently reported by The Wall Street Journal · Date: August 17, 2026
What is being said: Defense Secretary Pete Hegseth appeared with Nunn at the Iowa State Fair and urged that Nunn remain in Congress, while stating that he was appearing in a personal capacity.
What the record shows: The Wall Street Journal reported that Hegseth gave an approximately 19-minute campaign speech, said Nunn had asked him to come, called the appearance an “absolute no-brainer,” and said Washington needed Nunn to continue serving. Hegseth also said, “According to the lawyers, I’m only here in a personal capacity today.”
IA Fact Check assessment: Documented campaign support; personal-capacity disclaimer is on the record. A Hatch Act violation is not established by the appearance alone.
Context / limits: U.S. Office of Special Counsel guidance permits substantial partisan activity by less-restricted federal employees and contains special rules for certain presidential appointees confirmed by the Senate, while continuing to restrict misuse of official authority, titles, government resources and political fundraising. IA Fact Check located no OSC ruling or other adjudication finding this specific Aug. 17 appearance unlawful.
Embedability: No stable primary-source player for the full event was located; the contemporaneous report and official Hatch Act guidance are linked rather than embedding an unverified repost.

Democratic opposition material says Nunn has never held a public town hall during his congressional tenure.
IA Fact Check assessment: Checkable claim, but “town hall” definition matters
The narrow question is whether Nunn held an open, publicly accessible constituent town hall, not whether he attended public events, roundtables or invitation-only meetings. The claim should be updated if an open event meeting the ordinary town-hall definition is documented.
2026 reelection launch video
Sponsor: Zach Nunn for Congress · Date: 2026 filing period
Nunn’s reelection launch presents his military biography, constituent coalition and congressional record as the case for another term in Iowa’s 3rd District.
IA Fact Check assessment: Candidate promotional media — claims should be checked individually
This is candidate-produced promotional media, so it is useful primary evidence of how Nunn is presenting his record but not independent validation of broad claims such as support from “every corner” of the district or the effect of his legislative work. Those claims remain auditable through election, congressional and voting records.

Federal Election Commission data through June 30, 2026 show Zach Nunn with $4.87 million in total receipts, $1.35 million in total disbursements and $3.57 million cash on hand. Iowa Capital Dispatch summarized the latest quarterly period as $722,310 raised and $314,446 spent.
IA Fact Check assessment: Supported public record — not a misconduct finding
FEC totals document the campaign’s reported financial position. They do not by themselves prove donor influence, corruption, candidate popularity or likely election outcome.
This profile separates documented actions and quotations from campaign interpretation. Where an opponent uses a political label, the label is presented as advocacy rather than converted into a factual finding unless the underlying evidence supports the narrower claim.
