Greg Landsman

A Democratic primary challenger in Ohio has launched a website calling incumbent Rep. Greg Landsman "Genocide Greg."

The website claims Landsman is "bought and paid for" by pro-Israel lobbyists, citing his vote against a war powers resolution for Iran.

The challenger's website and other sources show differing amounts for pro-Israel PAC contributions to Landsman's campaign.

Rep. Greg Landsman, a Cincinnati Democrat who has broken with his party on several major votes, is now being accused by his primary opponent of supporting "genocide."

Damon Lynch IV, a Cincinnati Democrat challenging Landsman in the May primary, launched a website referring to Landsman as "Genocide Greg" with claims that Landsman is "bought and paid for" by pro-Israel lobbyists.

Landsman has drawn criticism from Lynch and Cincinnatians on social media after he was one of four Democrats to vote against a war powers resolution to stop military action in Iran without congressional approval.

Landsman has since said he would vote in favor of the next war powers resolution to come before the U.S. House of Representatives. He told attendees of a town hall in Lebanon on March 22 that it's time for the U.S. to be done in Iran.

Landsman won reelection in 2024, defeating Republican Orlando Sonza with 56% of the vote. Ohio lawmakers redrew the congressional districts in October 2025. Ohio's 1st District now includes Clinton County, Warren County and parts of Hamilton County. It leans slightly Republican, according to composite data from Dave's Redistricting.

Lynch told The Enquirer he launched the website to let voters know about the Landsman's votes and "the damage he's done."

The site includes donation numbers Lynch said come from Track AIPAC, a website dedicated to documenting the contributions the American Israel Public Affairs Committee makes to federal officials. The donation numbers on Lynch's website differ from the AIPAC contributions listed by the Federal Elections Commission and OpenSecrets, a nonprofit organization that tracks money in politics.

Landsman received $415,658 in contributions from pro-Israel political action committees and employees as of 2024, according to OpenSecrets.

The split over Israel is playing out in Democratic primaries across the country, with AIPAC and its lobbying clout a top target. But so far no Democratic incumbent has lost.

What did Greg Landsman say?

The Enquirer reached out to Landsman's campaign via email and Landsman himself by text message. Landsman said he did not want to "participate" in the story and shared information from the World Jewish Congress about accusing Israel of genocide.

Hamilton County Democratic Party Chair Alex Linser offered this reaction: "The stakes in this election are incredibly high and we cannot get distracted. Republicans in Columbus and in Washington have sent the cost of living skyrocketing and ripped away healthcare from millions."

Linser said that Landsman has delivered on those issues by working to secure Social Security benefits for teachers and public servants, among other things.
