US lawmakers are seeking information from Health Secretary Robert F. Kennedy Jr. regarding a vaccine settlement.

The inquiry comes after Merck agreed to pay $50 million to settle litigation over Gardasil. Four Democratic senators have asked Kennedy if his family will benefit from the payout, given his past involvement as an attorney of record in some related cases. Further details on this matter can be found in the Waco Tribune-Herald, which has reported on the senators' inquiry and Merck's settlement agreement.
