Sen. Chris Van Hollen (D-MD) on Thursday called out recent AIPAC and crypto-linked spending in the crowded Democratic House primary in Maryland to replace retiring Rep. Steny Hoyer (D-MD), accusing “outside groups” of “trying to buy this congressional seat.”

“I think voters need to be aware that these outside groups do not have the voters’ interests at heart,” he said during a press conference.

His comments came days after AIPAC’s super PAC, United Democracy Project, invested more than $1 million in a television ad buy to boost Adrian Boafo, a Maryland state delegate endorsed by Hoyer as well as other prominent Democrats in the state.

In a statement to Jewish Insider, Patrick Dorton, a spokesperson for UDP, shot back at the senator, an outspoken critic of Israel who in March called AIPAC anti-American in an address to the progressive Israel advocacy group J Street. “Once again, Chris Van Hollen is deliberately misrepresenting our views and discriminating against millions of pro-Israel Democrats who are members of AIPAC,” Dorton said.

Van Hollen, who is seen as a possible presidential contender in 2028, has not issued an endorsement in the June 23 primary to represent Maryland’s 5th Congressional District — making him a high-profile holdout among state leaders who have thrown their support behind Boafo, including Gov. Wes Moore and Sen. Angela Alsobrooks (D-MD).

Dorton called Boafo, viewed as a favorite to win the nomination, “a strong and principled Democratic fighter,” and said UDP is “proud to stand with leaders like Gov. Wes Moore, Sen. Angela Alsobrooks and Congressman Steny Hoyer to help get him elected.”

Boafo, for his part, said he agreed with Van Hollen “that big money has no place in politics” and vowed to “work with him in Congress to end Citizens United once and for all,” referring to the Supreme Court decision that struck down limits on independent political spending by corporations. 

“My campaign has been laser focused on the issues of affordability, health care and standing up to this president who has destroyed our economy, including our federal workforce,” Boafo said in a statement to JI shared by a campaign spokesperson, adding that his “coalition is focused on delivering results to the people of Maryland’s 5th District.”

The packed primary also includes Rushern Baker, a former Prince George’s County executive; state Sen. Arthur Ellis; Quincy Bareebe, who challenged Hoyer in 2024; and Harry Dunn, the former Capitol police officer who ran for a separate House seat in Maryland last cycle and drew outside attacks from UDP that are fueling his renewed criticism of its engagement in his current race.

In a recent statement denouncing the group, Dunn accused Boafo of “benefiting from the MAGA donors who fund AIPAC.”

Boafo, 32, is also backed by Democratic Majority for Israel’s super PAC — which is led by Brian Romick, a former chief of staff to Hoyer.

“We support Adrian Boafo and believe he’s the best candidate for the district,” Romick said in a statement to JI. “We hope Sen. Van Hollen will vocally and specifically oppose all super PAC spending, and not just the spending he disagrees with.”

In his remarks on Thursday, Van Hollen suggested candidates who accept AIPAC’s financial backing are not aligned with prevailing Democratic sentiment on Middle East policy.

“I don’t think it’s any secret that voters do not support unconditional votes in support of the conduct of the government of Israel,” he said, while adding, “For a long time AIPAC has had a pretty free hand.”
