U.S. Attorney General Pam Bondi said a "coward hiding behind a keyboard" was arrested Tuesday for allegedly sending a threatening letter to conservative influencer Benny Johnson in the wake of Charlie Kirk’s assassination. 

George Isbell Jr. was detained this morning and he will be federally charged with mailing threatening communications, according to Bondi. Johnson has a home in Tampa, Florida, where the announcement of the arrest was made. 

"Benny is a well-known media personality, carrying a message very similar to Charlie's. Grounded largely in faith and love of country. Just days after Charlie's assassination, Benny received a letter at his home where he and Kate are raising their beautiful, beautiful young family," Bondi said. "The author of this letter made it very clear that he hated Benny because of his views, and he wanted Benny dead." 

"This was a coward hiding behind a keyboard who thought he could get away with this. That's why we're standing up here today. You are not going to get away with threatening people in this way. And I'm proud to announce that we have arrested the author of this letter," Bondi added.

She said earlier that, "we've been living through a horrific cycle of political violence in this country." 

"We are going to catch you if you think you can do something like this," Bondi declared. "We don't care if you're across the country in California, we will find you. We will arrest you, we will extradite you, and we will bring you to justice. We cannot allow this political violence to continue any longer. This arrest will serve as a reminder to many – do not do this. We will find you." 

U.S. Attorney Gregory Kehoe for the Middle District of Florida told reporters Friday that Johnson "immediately contacted" the Tampa Police Department after receiving the letter. The FBI and the Florida Department of Law Enforcement assisted in the investigation, while the U.S. Postal Service determined the letter originated from San Diego, California, Kehoe added.

Fingerprints that were obtained from the letter led investigators to Isbell, according to Kehoe. 

"He is calling for the extermination of Mr. Johnson. That he should be strangled by an American flag, that he hoped somebody blows his head off. And then some vicious, vicious comments thereafter," Kehoe said about the letter. 

Speaking himself, Johnson said, "I don't want political violence. I want peace in my nation." 

"I love this country. I want to be able to debate like Charlie did. I want to be able to raise my family in peace. That is our birthright. But you cannot make peace with evil as a Christian. You cannot unite with people who want you dead. I want unity in this nation," he added.
