The nation's top infectious disease expert, Dr. Anthony Fauci, will step down from his roles running the National Institute of Allergy and Infectious Diseases and advising the White House at the end of the year.

He became a quasi-celebrity because of his steadfast commitment to science, challenging former President Donald Trump on everything from the use of hydroxychloroquine to mask mandates.

The 81-year-old has advised seven U.S. presidents, starting with Ronald Reagan through the HIV/AIDS epidemic.

Fauci said that he has no plans to retire.

Fauci plans to pursue the next phase of his career after more than 50 years of government service. I want to use what I have learned as NIAID Director to inspire and mentor the next generation of scientific leaders as they help prepare the world to face future infectious disease threats.

He joined the National Institute of Health at the age of 27 and rose through the ranks to become the director of the National Institute of Allergy and Infectious Diseases.
