A Pennsylvania man faces up to 10 years in prison for allegedly threatening to kill FBI agents in the days after federal investigators searched former President Donald Trump’s Mar-a-Lago home in search of classified documents.

Adam Bies, 46, of Mercer, was arrested Friday on charges of making threats of violence against FBI personnel, the Justice Department said Monday. 

According to a criminal complaint, Bies made a series of violent threats about the FBI last week on the social media platform Gab. A private group that tracks far-right extremists, MEMRI Domestic Terrorism Threat Monitor, tipped off the FBI’s National Threat Operations Section about Bies’ alleged online activity, the Justice Department said.

According to the criminal complaint, Bies, using the handle “BlankFocus,” posted Aug. 10: “Every single piece of s*** who works for the FBI in any capacity, from the director down to the janitor who cleans their f****** toilets deserves to die. You’ve declared war on us and now it's open season on YOU.”

That same day, he allegedly posted: “HEY FEDS. We the people cannot WAIT to water the trees of liberty with your blood. I’ll be waiting for you to kick down my door.”

In another post on Aug. 11, Bies wrote he believed it was inevitable that he’d “die at the hands of these piece of s*** child molesting law enforcement scumbags,” adding: “My only goal is to kill more of them before I drop. I will not spend one second of my life in their custody,” according to the criminal complaint.

Court records do not list an attorney for Bies.

Bies’ arrest came a day after Ricky Shiffer, a 42-year-old Iraq War veteran, tried to enter the FBI’s Cincinnati office with an AR-15-style rifle and nail gun, fled and was later fatally shot by police following a standoff, according to authorities. Shiffer appeared to have posted messages on Trump’s Truth Social platform calling for FBI agents to be killed following the Mar-a-Lago search on Aug. 8.

Republican politicians unleashed a wave of unrelenting criticism of the FBI and Justice Department immediately after Trump revealed the Mar-a-Lago search. For example, Rep. Paul Gosar of Arizona tweeted, “We must destroy the FBI.” Without evidence, Trump has suggested FBI agents may have planted incriminating evidence, a sentiment echoed by Sen. Rand Paul of Kentucky and Fox News host Jesse Watters. Former Trump adviser and podcaster Steve Bannon has said Republicans are “at war” with the federal government, while some GOP candidates have called for states to cut ties with federal agencies.

Others, including House Minority Leader Kevin McCarthy — who is in line to become speaker if Republicans win control of the House this fall — have vowed to investigate the Justice Department and FBI over the Mar-a-Lago search. 

FBI Director Christopher Wray last week called threats circulating online against federal agents and the Justice Department “deplorable and dangerous.” And, according to multiple reports, the Departments of Justice and Homeland Security released a joint intelligence briefing warning that law enforcement officers and other government officials are facing increasing threats since the FBI operation at Trump’s home.

"Since the search, the FBI and DHS have observed an increase in violent threats posted on social media against federal officials and facilities, including a threat to place a so-called dirty bomb in front of FBI Headquarters and issuing general calls for 'civil war' and 'armed rebellion,'" the bulletin says.
