A key member of the White House coronavirus task force, Dr. Anthony Fauci, reportedly now has increased security due to alleged threats. He tells TODAY’s Savannah Guthrie: “I’ve chosen this life … there are things about that are sometimes disturbing but you just focus on the job you have to do and put all that other stuff aside and just forge ahead.” He says he’s “physically fine” even though his voice is hoarse from briefings and interviews: “I just need to keep my mouth shut.”
