Scalise, Comer say Fauci must testify about published emails, COVID-19 origin Brooke Singman EXCLUSIVE: House Republicans say it is "imperative" for Dr. Anthony Fauci to testify before congressional committees and provide information related to the origins of COVID-19. House Republican Whip Steve Scalise, R-La., who serves as the top Republican on the House Select Subcommittee on the Coronavirus Crisis, and House Oversight Committee Ranking Member James Comer penned a letter to top Democrats on the committees, Chairman James Clyburn, D-S.C., and Carolyn Maloney, D-N.Y., saying it is "imperative" that Fauci appear before the committees. Scalise and Comer wrote that Fauci’s emails, which were released through a Freedom of Information Act filing this week, "debunk many Democrats’ claims from the past year," including that he and other scientists were "‘muzzled’" by the Trump administration.
