aerosol, a position which other experts have criticized. In 2020 he became a coronavirus advisor to the Trump White House, where he strongly promoted the use of hydroxychloroquine to treat the virus despite FDA objections to the drug. After the 2020 election he became part of Donald Trump's attempt to overturn the election results. Early life Hatfill was born in Saint Louis, Missouri, and graduated from Mattoon Senior High School, Mattoon, Illinois (1971), and Southwestern College in Winfield, Kansas (1975), where he studied biology. Hatfill was enlisted as a private in the U.S. Army from 1975 to 1977. (In 1999, during an interview with a journalist, he claimed to have been a "captain in the U.S. Special Forces", but a subsequent investigation revealed that, according to the Army, he had never served with the Special Forces.) Following his Army discharge, Hatfill qualified and worked as a medical laboratory technician, but soon resolved to become a doctor. He worked as a medical missionary in Kapanga, Zaire under a mentor, Dr. Glenn Eschtruth, who was murdered there in 1977. A brief marriage, from 1976 to 1978, to Eschtruth's daughter, Caroline Rush Eschtruth, produced one daughter. Medical education In 1978, Hatfill settled in Rhodesia (now Zimbabwe) and entered the Godfrey Huggins Medical School at the University of Rhodesia in Salisbury (now Harare). (His claimed military associations during this period included assistance as a medic with the Selous Scouts and membership in the Rhodesian SAS, but according to one journalist the regimental association of the latter is "adamant Hatfill never belonged to the unit".) After failing in 1983, he graduated in 1984 with a M ChB degree and, in 1984 to 1985, completed a one-year internship at a small rural hospital in South Africa's North West Province. The South African government recruited him to be medical officer on a 14-month tour of duty, from 1986 to 1988, in Antarctica with the South African National Antarctic Expedition (SANAE). In 1988, he completed a master's degree in microbiology at the University of Cape Town. Two years later, he worked toward a second master's degree—in medical biochemistry and radiation biology—at the University of Stellenbosch, while employed as a medical technician in the university's clinical hematology lab. A three-year hematological pathology residency at Stellenbosch from 1991 to 1993 followed. Hatfill also conducted research toward a Ph.D. between 1992 and 1995—under the supervision of microbiology professor Ralph Kirby at
