A 56-year-old man is facing federal charges for threatening to harm the nation’s leading infectious disease expert, Dr. Anthony Fauci, according to Maryland officials.

In a complaint, which was filed Tuesday, the Maryland Department of Justice said that Thomas Patrick Connally, Jr. sent Fauci, as well as the current Director of the National Institutes of Health Dr. Francis Collins, a series of threatening emails from Dec. 28, 2020 to July 21, 2021.

Connally used an encrypted email account from a provider based in Switzerland to send the emails to Fauci, where he threatened to harm and kill him as well as members of his family. In one email, Connally said Fauci and his family would be “dragged into the street, beaten to death, and set on fire.”

The complaint, which was obtained by Business Insider, also detailed an instance where Connally called Fauci a "lying sack of [explitive]” and "a sickening, compromised satanic freemason criminal."

In another email, Connally sent Fauci seven threatening emails in one day over a span of seven minutes. Fauci, a steadfast proponent of mask-wearing, lockdowns and vaccinations, had received four emails from Connally just 30 minutes prior.

According to court documents, Connally appeared to have a grudge against Fauci for his views on the COVID-19 vaccine as one email about Fauci and his wife said that they would “have the teeth smashed out of its worthless [expletive] if you say ONE MORE WORD about 'mandatory vaccines,’” Business Insider reported.

An investigation revealed that the encrypted email account belonged to Connally and a search warrant was obtained for his mail.com account.

Connally faces a sentence of up to 10 years in federal prison for threats against a federal official and a maximum of five years in federal prison for interstate communication containing a threat to harm if convicted.

“We will never tolerate violent threats against public officials,” Acting U.S. Attorney Jonathan Lenzner said in a statement. “Our public health officials deserve our thanks and appreciation for their tireless work, and we will not hesitate to bring charges against those individuals who seek to use fear to silence these public servants.”
