Fauci contempt vote clears key Senate committee in COVID probe; why is he being questioned now?

A Senate committee voted to hold Dr. Anthony Fauci in contempt of Congress. This action stems from his refusal to answer questions during a hearing. Fauci invoked his Fifth Amendment right over one hundred times during the proceedings. Republicans are scrutinizing the government's pandemic response and virus origins. Democrats opposed the move, calling the investigation politically motivated.
