Kennedy Jr. is revising his ethics agreement to divest his interest in litigation against an HPV vaccine maker and directing the stake to his adult son, The New York Times reported Friday, citing a written response to questions from senators who are weighing his confirmation as Health and Human Services secretary.

RFK Jr. claimed he is not “anti-vaccine” and appeared unfamiliar with key aspects of healthcare insurance programs in his confirmation hearing.

While Mr. Kennedy, seeking the job of health secretary, has been vocal about vaccines and his desire to overhaul the nation’s diet, he has said very little about other issues.

The health committee chairman, Sen. Bill Cassidy, R-La., also has expressed concerns about Kennedy's anti-vaccine work. A physician, Cassidy said earlier this month he “had a frank conversation” and “spoke about vaccines at length” with Kennedy. On Tuesday, Cassidy told reporters that he is still unsure if he is backing Trump’s nominee.

The hearings were packed to capacity with protesters and fans, while the spillover crowd hung out in hallways and overflow rooms.

Robert F. Kennedy Jr. also disclosed that he had reached at least one settlement agreement with a company or individual that has accused him of “misconduct or inappropriate behavior.”

The top Republican on the Senate's health committee, Sen. Bill Cassidy, R-La., faced criticism from fellow Republicans after he suggested his vote for Robert F. Kennedy Jr.'s confirmation as Health and Human Services secretary is not a lock.
