Katherine Clark

UnitedHealth Group’s top executives, including CEO Stephen Hemsley, and company board members recently flooded the campaign coffers of Rep. Katherine Clark of Massachusetts, the No. 2 Democrat in the House who just beat two opponents in a closely watched primary race.

More than 40 officials and board members across UnitedHealth cumulatively donated more than $100,000 to Clark’s campaign during the 2025-2026 election cycle, a STAT analysis of federal records shows. Leading the way was Hemsley and his wife, Barbara, who donated $7,000 each to Clark’s political fund. Hemsley is worth almost $1 billion between his previously exercised stock and remaining stock ownership in UnitedHealth.

The only other federal politician who received even half that amount from UnitedHealth employees this election period was Sen. Mike Crapo (R-Idaho), who is not up for reelection this November.
