Massie introduces AIPAC Act as $25.6M floods his primary

$25.6M in PAC money targets a 13-year incumbent over Israel votes·May 15, 2026

Rep. Thomas Massie introduced H.R. 8809 on May 15, 2026, four days before his Kentucky Republican primary. The bill would force AIPAC to register as a foreign agent under the 1938 Foreign Agents Registration Act. His race against Trump-backed Ed Gallrein has drawn $25.6 million in ad spending, making it the most expensive U.S. House primary in history. AIPAC''s United Democracy Project spent $2.6 million, the Republican Jewish Coalition spent $4 million, and MAGA KY spent $5.6 million opposing Massie. The billionaire donors behind MAGA KY include Paul Singer, who also ranks as a top AIPAC funder. Massie says 95% of funding against him comes from pro-Israel groups. The race tests whether outside PAC money combined with a presidential endorsement can oust a 13-year incumbent who won his last primary uncontested.

Key facts

Rep. Thomas Massie (R-KY) introduced H.R. 8809 on May 15, 2026, a bill he calls the Americans Insist on Political Agent Clarity Act. It would amend the Foreign Agents Registration Act to require AIPAC to register with the Department of Justice as a foreign agent. Massie filed it four days before the May 19 Kentucky Republican primary where he faces Trump-endorsed challenger Ed Gallrein.

The bill has no cosponsors. AIPAC currently registers under the Lobbying Disclosure Act as a domestic entity because its members and donors are American citizens, not employees of the Israeli government.

The Kentucky 4th District race has drawn $25.6 million in ad spending, breaking the record set by New York's 16th District Democratic primary in 2024 ($25.4 million). Federal Election Commission data shows roughly $35 million in total campaign costs when non-ad expenses are included.

Of the ad total, $14.3 million supports Gallrein and $10.7 million supports Massie. The lopsided outside spending against a sitting congressman in a safe Republican district is unprecedented in a GOP primary.

AIPAC's United Democracy Project spent $2.6 million on anti-Massie ads. The Republican Jewish Coalition dropped $4 million backing Gallrein. MAGA KY, a super PAC run by former Trump co-campaign manager Chris LaCivita and pollster Tony Fabrizio, spent $5.6 million attacking Massie.

MAGA KY's top individual donor is Paul Singer, a billionaire hedge fund manager who also ranks among AIPAC's largest funders. Casino magnate Miriam Adelson's affiliated super PAC and hedge fund manager John Paulson together contributed $2 million to MAGA KY.

Massie told Tucker Carlson on May 7 that pro-Israel groups fund at least 95% of spending against him. He named AIPAC, the Republican Jewish Coalition, Christians United for Israel, Paul Singer, Miriam Adelson, and John Paulson. CUFI Action Fund ran a six-figure billboard campaign showing Massie under an Iranian flag opposite Trump under an American flag.

In the same interview, Massie called AIPAC a foreign interest group and said it demanded 16 votes on Israel in a single month of April from House Republicans.

Ed Gallrein is a retired Navy SEAL and Army Ranger with 30 years of military service, four Bronze Stars, and two Presidential Unit Citations. He announced his candidacy in October 2025 and received Trump's endorsement in early November 2025. Trump visited Boone County in March 2026 and brought Gallrein onstage.

A Quantus Insights poll released May 13 showed Gallrein leading Massie 53% to 45%, an eight-point margin in a district Massie has held since 2012.

Massie is one of few Republicans who consistently votes against Israel-related legislation. He cast the sole Republican vote against the 2021 Iron Dome funding bill, the sole GOP vote against a 2022 resolution denouncing antisemitism, and the only Republican no on a 2023 resolution backing Israel's military actions in Gaza (that resolution passed 412-10). His broader pattern is opposing all foreign aid.

Massie frames these votes as fiscal conservatism, not hostility toward Israel. Pro-Israel groups frame them as dangerous isolationism.

MAGA KY ran an AI-generated deepfake ad showing Massie in a fake romantic scene with Rep. Alexandria Ocasio-Cortez and Rep. Ilhan Omar. Rep. Marjorie Taylor Greene (R-GA) publicly condemned the ad, calling it a violation of the Take It Down Act that Trump signed into law.

The incident split Trump allies: Greene defended Massie while the PAC run by Trump's own former campaign managers produced the ad.

The Foreign Agents Registration Act dates to 1938, originally targeting Nazi propaganda. It requires anyone acting at the direction or control of a foreign government to register with DOJ and disclose activities. AIPAC's predecessor, the American Zionist Council, was ordered to register under FARA in 1962 by Attorney General Robert Kennedy's DOJ after investigators documented $5 million in transfers from the Jewish Agency for Israel.

The AZC dissolved its lobbying functions. AIPAC incorporated separately in 1963 and obtained domestic classification. DOJ has not revisited that determination since.

Massie's bill faces near-zero chance of passage in a Republican-controlled House where AIPAC maintains relationships with the vast majority of members. But the legislation forces a public debate about whether organizations that coordinate closely with a foreign government's policy goals should register under FARA even when their funding comes from domestic sources.

The DOJ's FARA Unit conducted 26 inspections in 2024, its most active year since 1977, signaling increased enforcement interest regardless of Massie's bill.

Kentucky's 4th District covers northern Kentucky suburbs of Cincinnati and stretches into rural eastern counties. It's 87.9% white with 75.4% homeownership. Massie ran uncontested in 2024. The district voted heavily for Trump in 2020 and 2024.

The core question for voters on May 19 is whether Massie's libertarian conservatism and opposition to foreign aid outweighs a presidential endorsement backed by $14.3 million in outside spending. No sitting House Republican has faced this level of coordinated PAC spending in a primary.
