Four Democratic senators sent a letter Monday to Health and Human Services Secretary Robert F. Kennedy Jr. demanding to know whether he or his family stand to profit from a $50 million settlement Merck reached to resolve litigation over its HPV vaccine Gardasil.
The letter zeroes in on a specific conflict: Kennedy played a direct role in building the legal challenge to Gardasil before taking over HHS, and the senators want to know whether he fully divested any financial interest in that lawsuit before assuming oversight of federal vaccine policy.
Merck agreed earlier this year to pay $50 million to settle the Gardasil litigation. The vaccine prevents cancers caused by the human papillomavirus and is one of the most widely administered vaccines in the United States. Kennedy spent years publicly attacking the vaccine's safety record before his confirmation as HHS secretary.
The four senators did not publicly allege that Kennedy retained a financial stake—they raised the question and demanded documentation. Their central concern is whether Kennedy's divestment was genuine and complete, or whether members of his family are positioned to collect from the settlement while he runs the federal agency responsible for vaccine safety and approval.
As HHS secretary, Kennedy oversees the Food and Drug Administration and the Centers for Disease Control and Prevention, both of which play roles in evaluating and recommending vaccines including Gardasil. A financial interest—direct or through family—in litigation targeting a vaccine his own agency regulates would raise a textbook conflict-of-interest question under federal ethics rules.
Federal law requires senior executive branch officials to divest financial holdings that create conflicts with their official duties or to recuse themselves from matters where a conflict exists. The senators' letter presses Kennedy on which path he took and whether he can document it.
Kennedy's history with Gardasil litigation predates his government service by years. He was a prominent figure in the legal and advocacy campaigns against the vaccine, and his organization Children's Health Defense ran sustained campaigns questioning its safety. That background made his confirmation a flashpoint, with Republican-controlled committees advancing him over Democratic objections that focused in part on his vaccine positions.
The $50 million Merck settlement is large by pharmaceutical litigation standards but well below what plaintiffs' lawyers in similar cases have sought. Whether Kennedy or his family held contingency-fee arrangements, litigation funding stakes, or other financial interests in the outcome of that case is not publicly known—which is precisely what the senators say they are trying to determine.
The letter landed as Kennedy continues to face scrutiny from Senate Democrats who lack the votes to block his agenda but retain oversight authority to demand records and public explanations. Kennedy has not publicly responded to the letter. HHS did not release a statement as of Monday.
