Dr. Anthony Fauci faced intense scrutiny from Republican lawmakers over his alleged involvement in the origins of the Covid-19 virus during a congressional hearing.

A year-long investigation found no evidence of wrongdoing on Fauci's part, but tensions remained high as he defended himself against accusations related to a Chinese lab's role in the pandemic.

Fauci supported suspending funding to EcoHealth Alliance and emphasized the need for better pandemic preparedness and communication between federal and local health officials.

Republican Rep. Marjorie Taylor Greene refused to address Fauci as a doctor, prompting GOP Chairman Brad Wenstrup to remind her to show respect.

Fauci detailed threats he and his family have received, including death threats and harassment, expressing concern that these could deter future public health workers.

Democratic Rep. Jamie Raskin criticized Republicans for supporting Donald Trump's dangerous Covid-19 suggestions and defended Fauci against baseless accusations.

Other Democrats, including Rep. Kathy Castor and Rep. Raul Ruiz, supported Fauci, aiming to deflect attention from the Trump administration's failures during the pandemic.

The discussion also touched on vaccine mandates, the importance of understanding the virus's origins for policy decisions, and the increased isolation and decline in health among residents in long-term care homes due to visitor restrictions.
