Top U.S. infectious disease scientist Dr. Anthony Fauci is disavowing a Trump campaign commercial that he says took his words out of context. The ad features these remarks, selectively edited from an interview Fauci gave back in March.

Dr. Anthony Fauci: “I can’t imagine that … anybody could be doing more.”

Dr. Fauci has never endorsed a political candidate in more than 35 years of public service. In a statement, he responded, “The use of my name and my words by the G.O.P. campaign was done without my permission, and the actual words themselves were taken out of context, based on something that I said months ago regarding the entire effort of the task force.”
