Grant Smith, a lawyer for Mr. Stone, was among the followers who had joined Mr. Caputo’s talk on Sunday. Mr. Caputo has 5,000 Facebook friends, and his video was viewed more than 850 times. He has now shut down his account.
Over all, his tone was deeply ominous: He warned, again without evidence, that “there are hit squads being trained all over this country” to mount armed opposition to a second term for Mr. Trump. “You understand that they’re going to have to kill me, and unfortunately, I think that’s where this is going,” Mr. Caputo added.
In a statement on Monday, Mr. Caputo told The Times: “Since joining the administration, my family and I have been continually threatened” and harassed by people who have later been prosecuted. “This weighs heavily on us, and we deeply appreciate the friendship and support of President Trump as we address these matters and keep our children safe.”
He insisted on Facebook that he would weather the controversies, saying, “I’m not going anywhere.” And he boasted of the importance of his role, stating that the president had personally put him in charge of a $250 million public service advertising campaign intended to help the United States return to normal.
The Department of Health and Human Services is trying to use that campaign to attract more minority volunteers for clinical trials of potential Covid-19 vaccines and to ask people who have recovered to donate their blood plasma to help other infected patients. Department officials have complained that congressional Democrats are obstructing the effort.
While Mr. Caputo characterized C.D.C. scientists in withering terms, he said the agency’s director, Dr. Robert R. Redfield, was “one of my closest friends in Washington,” adding, “He is such a good man.” Mr. Caputo is partly credited with helping choose Dr. Redfield’s new interim chief of staff.
Critics say Dr. Redfield has left the Atlanta-based agency open to so much political interference that career scientists are the verge of resigning. The agency was previously seen as mostly apolitical; its reports were internationally respected for their importance and expertise.
