(EPA PHOTO)US infectious diseases expert Anthony Fauci says there is an "unhinged" campaign to see him jailed. "Under the advice of my attorneys, I will invoke my right under the Fifth Amendment of the Constitution to refrain from answering your questions," Fauci told the Senate Homeland Security and Governmental Affairs Committee, in his opening statement on Wednesday. Fauci declined to answer 15 questions from Republican Senator Rand Paul, invoking his Fifth Amendment rights for each of them. A review of his public record provided by a representative of Fauci shows his positions were consistent with the diary.
