Dr. Matthew Memoli, a National Institute of Allergy and Infectious Diseases researcher focused on flu and other respiratory viruses, has been named acting director of the nearly $50 billion agency.

Previously, the CIA did not take a position on where the virus - which is responsible for more than seven million deaths worldwide - came from.

Sen. Rand Paul (R-KY) issued 14 bipartisan subpoenas for Biden-era federal departments to continue COVID-19 origins investigations.

President Donald Trump has ended the federal security detail for Dr. Anthony Fauci, the infectious disease expert who advised him on the COVID-19 pandemic.

The past three administrations have tried to limit gain-of-function research. The second Trump administration might be the first one to be successful at doing so.

Rand Paul condemned Biden for issuing a pardon to Dr. Anthony Fauci for all crimes he may have committed as one of his last acts in the White House.

"Dr. Fauci saw that and he said, 'Oh my God, I could get blamed for all this. So I'm going to have to establish complete control so nobody has questions'"

Dr. Anthony Fauci’s federal security protection was withdrawn, with President Trump advising him to arrange private security. Fauci’s controversial role in shaping the COVID-19 pandemic response earned praise and criticism.

In addition to Fauci, Biden also granted pardons to General Mark Milley, the Members of Congress and staff who served on the Select Committee to Investigate the January 6th Attack on the United States Capitol, and the US Capitol and D.C. Metropolitan police officers who testified before the Select Committee.
