A Virginia man is facing federal charges of making online threats against Vice President Kamala Harris, the Democratic presidential nominee.

Frank Lucio Carillo, 66, was arrested Friday at his home in Winchester, Virginia. Authorities say Carillo made more than 4,300 posts on the conservative social media platform GETTR that also targeted President Joe Biden, FBI Director Christopher Wray and other public officials. 

Harris was mentioned 19 times in posts made by an account linked to Carillo, authorities said. They began less than a week after Biden dropped out of the presidential race and Harris announced her candidacy.

In a July 27 post directed at Harris, Carillo allegedly wrote that she does not have “a snowballs chance in hell” and that he “will cut your eyes out of your [expletive] head while you're alive.” In another on the same day, he wrote he would “find you and your [expletive] family and I’m going to kill you all,” according to the criminal complaint.

In February, well before Harris was running for president, Carillo posted, “I HAVE MY AR-15 LOCKED AND LOADED,” authorities said.

The FBI began investigating Carillo after officials in Maricopa County, Arizona, alerted the agency about potential threats made on GETTR about the county recorder.

After obtaining internet protocol, mobile device and other information it believes linked an online alias and the posts to Carillo, the FBI searched his home and arrested him. According to the criminal complaint, Carillo told agents, “This is all over a comment, huh?” and then urged them not to arrest a woman he lives with, saying: “She didn’t do anything. I made the comments.”

Agents seized a 9 mm pistol, an AR-15 rifle and thousands of rounds of ammunition from Carillo’s home, authorities said.

Carillo made his initial court appearance Monday. Another hearing is scheduled for Thursday, court records show. He faces up to five years in prison if convicted.

“Open political discourse is a cornerstone of our American experience,” U.S. Attorney Christopher R. Kavanaugh of the Western District of Virginia said in a statement Monday. “We can disagree. We can argue and we can debate. However, when those disagreements cross the line to threats of violence,  law enforcement must step in.”

Carillo's attorney, Andrea Harris, declined to comment on the case to Spectrum News.

Last month, a gunman fired on former President Donald Trump, the Republican presidential nominee, striking him in the ear during a Pennsylvania campaign rally, killing one rallygoer and wounding two others. A Secret Service counter sniper killed the shooter.

An Atlanta man pleaded guilty last week to making death threats against Rep. Marjorie Taylor Greene, R-Ga.

Wray has repeatedly warned of “an elevated threat environment” for public officials. During a House Judiciary Committee hearing last month, he said it “reinforces our need at the FBI and our ongoing commitment to stay focused on the threats, on the mission and on the people we do the work with and the people we do the work for.”
