Robert F. Kennedy Jr. is distancing himself from his anti-vaccine work as he seeks to become the leader of the nation’s top health agency under President Donald Trump, according to government ethics documents released Wednesday.

Kennedy has pulled in roughly $10 million in income from his work over the past year, which includes speaking fees, leading an anti-vaccine nonprofit and legal fees, government ethics forms filed for his nomination show. He has millions of dollars more tied up in investments and other assets.

If confirmed, he has promised to stop collecting fees on some of his vaccine lawsuits involving the U.S. government.
