Herbert, a Republican, acknowledged that hydroxychloroquine for COVID-19, is "not without controversy," but said an $800,000 purchase from a local company whose CEO appeared alongside GOP lawmakers touting the drugs last month was part of the state's effort to make rational decisions based on "good science and good data."

Laura Kelly watches during a news conference in Topeka, Kan. Norman said of hydroxychloroquine that the state has no intention of buying the drug because there's not enough evidence it helps treat COVID-19. "It's just not been shown to be worthwhile," Norman said. "It hasn't been shown to be effective for COVID-19 patients in any disciplined professional study." (AP Photo/John Hanna,File)

After weeks of near-daily plugs for the use of hydroxychloroquine to help treat COVID-19 patients, Trump and the White House abruptly stopped discussing the drug a week ago. His promotion of the drug, based on isolated reports and instinct, frequently put him at odds with medical professionals, including Fauci, the nation's top infectious disease expert, who said evidence for the efficacy of the drug for COVID-19 patients was "anecdotal."

SALT LAKE CITY – In a story April 24, 2020, about states stockpiling the drug hydroxychloroquine, The Associated Press erroneously reported that 200 patients in South Dakota were being treated with the drug. Sanford Health says that as of Tuesday, there were 200 patients who have recovered from COVID-19 in a registry, and that some of them may have taken hydroxychloroquine, but it was not a requirement.
