Jim O'Neill, a top adviser to Health and Human Services Secretary Robert F. Kennedy Jr., will be the acting director of the Centers for Disease Control and Prevention.

This report comes one day after former CDC Director Susan Monarez was fired by the Trump administration.

The conflicting perspectives come amid an alleged internal struggle between Monarez and HHS Secretary Robert F. Kennedy Jr. regarding vaccinations and the alleged weaponization of public health.

Other former CDC officials have also strongly rejected the Trump administration's perceived weaponization of the public health system, with four long-term CDC officials resigning in the wake of news reports that Monarez was out of the agency.
