Live updates: Anthony Fauci refuses to answer Senate questions on Covid origins

Dr. Anthony Fauci declined to answer senators’ questions at a hearing Wednesday on the origins of Covid and the government’s handling of the pandemic, saying in prepared remarks that he would invoke his 5th Amendment right not to testify to avoid the possibility that Republicans could try to use his testimony to prosecute him for perjury. The surprise decision shook up the hearing, which was expected to be contentious given Fauci’s previous public clashes with Chairman Rand Paul, R-Ky.
