Dr. Vinay Prasad, a controversial critic of the US Food and Drug Administration who took a top role at the regulatory agency in May, has returned to his job weeks after resigning amid pressure from the White House and right-wing activist Laura Loomer.

Vinay Prasad recently drew outrage from conservatives, including Laura Loomer, who disagreed with his approach to approving gene therapies for rare diseases and accused him of holding liberal views.

Vinay Prasad, a top vaccine regulator ousted from the Food and Drug Administration (FDA) late last month, is set to return to his post, according to the Department of Health and Human Services (HHS).
