Republican Sen. Rand Paul of Kentucky has repeatedly said Fauci lies about the pandemic and in a hearing Tuesday also claimed that he tried to discredit scientists who disagreed with him.

The feud overshadowed a hearing of the Senate Health, Education, Labor and Pensions committee designed to examine if policy changes are needed while the U.S. is battling the hugely contagious omicron variant.

Later in Tuesday’s hearing, Fauci was heard muttering “what a moron” after Sen. Roger Marshall, R-Kansas, accused him of hiding financial disclosure forms that have long been public.
