Representative Seth Moulton, who is running against Senator Ed Markey in the Democratic primary, previously pledged to return all donations from the pro-Israel group AIPAC. However, campaign records show that Moulton has kept over $40,000 in AIPAC-linked contributions received in 2024, returning only about half of the total amount. Moulton's campaign now says it will only return donations received in the 2026 cycle, shifting from his original promise. While Moulton has made rejecting AIPAC support a major campaign theme, he has continued to accept donations from lobbyists connected to the government of Qatar, raising further questions about his fundraising practices.
