Sen. Rand Paul revealed Wednesday in a disclosure that was more than a year overdue that his wife in February 2020 bought up to $15,000 worth of shares in Gilead, a biotech company that brought to market the first drug designed to treat COVID-19. Paul’s mandatory filing with the Senate shows that his wife purchased between $1,000 and $15,000 worth of Gilead stock on Feb. 26, 2020. Gilead’s antiviral drug remdesivir became the first COVID-19 specific treatment to win an emergency use authorization from the Food and Drug Administration less that three months after the purchase in May 2020.
