""OpenSecrets, a nonprofit aimed at tracking money in U.S. politics, estimated Jeffries had received approximately $1,74 million through 2024 from pro-Israel donors generally, putting him slightly ahead of Senate Minority Leader Chuck Schumer. TrackAIPAC, an organization focused specifically on AIPAC and other pro-Israel lobbyists, connected $1.5 million in such donations to Jeffries.

AIPAC identified Jeffries by name in a congratulatory post on Nov. 4, writing on X (archived) that "AIPAC members are determined to expand their political activism in the cycles ahead.""
