U.S. Health Secretary Robert F. Kennedy Jr. received $4 million in advances for two books and accepted more than $270,000 in gifts last year from close associates involved with his Make America Healthy Again (MAHA) initiative, according to his recent financial disclosure. The revelations have prompted scrutiny over potential conflicts of interest and questions about Kennedy’s ability to maintain impartiality in his official role.

The advances, tied to two forthcoming books published by a company owned by Tony Lyons—a longtime friend and business ally of Kennedy—have drawn particular concern. Lyons also oversees several MAHA-affiliated organizations that engage in political advocacy and fundraising, including accepting contributions from health-related companies. Kennedy’s wife, Cheryl Hines, received $210,000 in consulting fees from MAHA Action, a nonprofit advocacy group led by Lyons that promotes Kennedy’s health agenda, including efforts to repeal federal liability protections for vaccine manufacturers.

While Kennedy pledged before taking office not to participate in the writing, editing, or promotion of these books during his tenure, he did not agree to relinquish advances. Ethics specialists noted federal rules prohibit officials from earning compensation for works related to their official duties while in office, raising questions about payments tied to a book titled "Unsettled Science," which addresses vaccine safety. The second book is "A Defense of Israel."

The arrangement has elicited criticism from former White House ethics counsel Richard Painter, who characterized the consulting payments to Hines from a group aligned with Kennedy’s policy goals as potentially reflecting a conflict of interest or appearance of a bribe.

In addition, Kennedy accepted nearly $126,000 in lodging in a Washington, D.C., residence owned by Gavin de Becker, a longtime friend and security firm operator who previously contributed to Kennedy’s presidential campaign and provided his security detail. De Becker also covered approximately $150,000 in airfare for Kennedy’s trips to Greece and Fiji. De Becker has denied any business ties with the federal government and described these arrangements as personal gestures between close friends.

Campaign Legal Center ethics counsel Kedric Payne noted that while federal rules allow certain exceptions for gifts from friends, the scale of de Becker’s contributions exceeded typical thresholds for such allowances and underscored the need for transparency about donor interests.

De Becker shares Kennedy’s skepticism of vaccine safety and has collaborated with Lyons in publishing related works. His 2025 book on alleged vaccine-related brain injury was published by Lyons’ company Skyhorse, which also provided Hines a $600,000 advance for her memoir.

Washington University law professor Kathleen Clark said these extensive gifts—from individuals who hold clear policy interests before the Department of Health and Human Services—create an undeniable conflict, compromising public confidence in Kennedy’s agency decisions related to vaccines and ketamine therapies, the latter of which Kennedy has endorsed for depression treatment and which are under HHS regulatory review.

The disclosure also indicates that Kennedy earned $451,000 last year as a consultant, and is set to receive $10,000 for a third book titled "America’s Path Back to Moral Leadership."

Lyons has expanded his network of MAHA-linked entities alongside Kennedy’s appointment, including the MAHA Center and MAHA Institute, which organize events attracting donors, advocates, and senior federal health officials. The upcoming MAHA Summit in Washington counts Grail—a company pursuing FDA approval for a multi-cancer blood test—as a top sponsor, despite the test’s poor performance in large trials.

MAHA Action actively supports legislative efforts, such as a bill introduced in 2025 to eliminate vaccine makers’ liability protections. Kennedy, who has litigated vaccine injury claims as a lawyer, has long opposed these legal shields enacted in 1986.

Meanwhile, MAHA PAC, also led by Lyons, raised over $3 million since January 2025, with significant contributions from Botanic Tonics, a company founded by Jerry W. Ross, who previously pleaded guilty to a financial crime. Ross has sought to influence Kennedy and the administration to ban 7-OH, a competing substance to his company’s kratom-based beverage, Feel Free. Both products have faced criticism for their potential addiction risks.

Last year, Senator Christopher S. Murphy questioned Kennedy at a Senate hearing about the influence of MAHA PAC donors. Kennedy denied knowledge of the group’s contributors and emphasized that the PAC’s positions align with his values.

The Department of Health and Human Services maintained that Kennedy complies with all applicable ethics laws and works with career ethics officials to manage disclosures and potential conflicts. Neither Lyons nor Hines responded to requests for comment.
