Fauci refuses to answer questions at heated US Senate hearing on Covid-19 origins
Republicans press former health official over Wuhan research funding as Democrats accuse committee of pursuing political vendetta

The extraordinary appearance reopened one of Washington’s most politically divisive disputes: whether the pandemic began through natural transmission from animals or a laboratory-related incident in Wuhan, and whether US officials adequately scrutinised research conducted there with American funding.
Fauci, who led the National Institute of Allergy and Infectious Diseases and became a prominent face of the US government’s Covid-19 response during the pandemic, was subpoenaed to appear on Wednesday before the Senate Homeland Security and Governmental Affairs Committee on the virus’s origins.
Committee chair Rand Paul, a Republican from Kentucky, has repeatedly accused Fauci of covering up evidence supporting the lab-leak theory tied to the Wuhan Institute of Virology in China.
