A 35-year-old mechanical engineer who worked as a contractor for the Federal Aviation Administration has been charged with threatening President Donald Trump after allegedly emailing the White House that he planned to "neutralize/kill" the president, months after searching assassination-related topics on a government-issued work computer, Mediaite reported.
Dean DelleChiaie of New Hampshire was arrested Monday and appeared in federal court Tuesday. He faces a charge of interstate communication of a threat against the president, which carries up to five years in prison and a $250,000 fine.
The charge lands barely a week after a separate armed attempt at the White House Correspondents' Dinner and amid a broader pattern of threats and violence directed at the president. For taxpayers who fund the federal workforce, the details in the case raise a pointed question: how did a man allegedly searching "I am going to kill Donald John Trump" on a government computer remain free for months before acting on the threat?
The timeline laid out in the case begins in January, when investigators say DelleChiaie used his FAA work computer to search topics including how to get a gun into a federal facility, support for killing the president, the vice president's home location, and the names of Vice President JD Vance's children. He also searched for details about the family of Defense Secretary Pete Hegseth, AP News reported, citing federal investigators.
On Feb. 3, a Secret Service agent and a Nashua police officer interviewed DelleChiaie at his apartment. An affidavit quoted by CBS News states that DelleChiaie admitted to conducting the searches.
He told investigators, in the affidavit's words:
"DELLECHIAIE stated he realized he should not search these subjects and that it was crazy for him to do this on his work computer."
He also offered a motive. The affidavit states:
"DELLECHIAIE expressed, in substance, that what motivated him to conduct these searches was that he upset with the current administration based on multiple subjects, including the election, presidential pardons, and the 'Epstein files.'"
Three months after the searches, on April 21, DelleChiaie allegedly sent the email that triggered the criminal charge. The message, sent to the White House, read in part:
"I, Dean DelleChiaie, am going neutralize/kill you, Donald John Trump, because you decided to kill kids, and say that it was War, when in reality, it is terrorism."
The email also stated: "God knows your actions and where you belong."
How did investigators first learn about the searches? AP News reported that DelleChiaie asked FAA IT staff to delete his search history. That request was flagged to authorities, which led to Secret Service involvement, his suspension from the FAA, and eventually his arrest.
The detail is worth pausing on. A federal contractor allegedly typed a direct threat against the sitting president into a taxpayer-funded computer, and the system caught it only because he tried to cover his tracks. Had he never contacted the IT department, the searches might have gone unnoticed until after the threatening email arrived at the White House, or worse.
Just The News reported that prosecutors say DelleChiaie told investigators he owned three firearms. The Secret Service agent who worked the case also noted that DelleChiaie had researched previous assassination attempts against the president, suggesting a level of study that goes well beyond idle frustration.
Even after the Feb. 3 interview, in which he admitted to the searches, DelleChiaie was not arrested on the spot. He remained free for more than two months before allegedly sending the threatening email on April 21. His arrest came weeks after that, on Monday.
The DelleChiaie case does not exist in isolation. It arrives against a backdrop of escalating threats and actual violence directed at President Trump and his administration. The 2024 shooting in Butler, Pennsylvania left Trump wounded. A few months later, another individual attempted to kill Trump at his Florida golf course.
Then, on April 25, just four days after DelleChiaie's alleged email, a gunman attempted to kill Trump and several members of his administration at the White House Correspondents' Dinner. The suspected shooter, 31-year-old Cole Tomas Allen, appeared to have been motivated by conspiracy theories about Trump and Jeffrey Epstein. Allen wrote in his manifesto that Trump was a "pedophile" and "rapist" who needed to be killed.
That incident was described as the third known assassination attempt against Trump since 2024. A federal judge later drew fierce backlash for apologizing to the accused shooter over jail conditions.
DelleChiaie's stated motivations, anger over the election, presidential pardons, and the "Epstein files", overlap uncomfortably with the conspiracy-fueled rage that prosecutors say drove Allen. The pattern is hard to ignore: individuals radicalized by online grievance, fixated on the same set of conspiracy theories, and willing to threaten or attempt lethal violence against a sitting president.
Several facts remain unclear. The source material identifies DelleChiaie both as a mechanical engineer "working for" the FAA and as a contractor. Whether he held a direct government position or a contract role matters, it affects the scope of background checks, security clearances, and the government's obligation to monitor workplace conduct.
The Washington Times reported that federal prosecutors described the January searches as covering assassination-related information and federal facility security, reinforcing the picture of deliberate research rather than a momentary outburst.
The specific federal court where DelleChiaie appeared Tuesday has not been identified in available reporting. Nor has the case number or the full charging document been made public in the accounts reviewed.
What is clear is the gap between detection and arrest. Law enforcement knew about the searches by early February. They interviewed DelleChiaie. He admitted what he had done. And yet the threatening email to the White House came more than two months later. Whether authorities had legal grounds to act sooner, or whether bureaucratic caution allowed a known threat to escalate, is a question that deserves a direct answer.
The broader security environment around the president has drawn sustained scrutiny. Separate incidents at Trump properties have also tested Secret Service readiness, including a physical confrontation with a Secret Service agent at Trump National Doral.
DelleChiaie now faces the possibility of five years in federal prison. That is the maximum. Whether he receives anything close to it will say something about how seriously the justice system treats direct threats against the president in an era when those threats have repeatedly turned into action.
The case also raises a more uncomfortable institutional question. The FAA, an agency already under intense public scrutiny for air safety and staffing, employed a contractor who allegedly used agency equipment to research killing the president. The IT staff did the right thing by flagging the deletion request. But the fact that a government computer was the vehicle for these searches in the first place points to gaps in monitoring that should concern every taxpayer funding the federal payroll.
Threats against the president have been prosecuted across a range of contexts in recent months. The common thread is that the rhetoric of political rage keeps finding its way into action, or into conduct serious enough to warrant federal charges.
When a man uses a government computer to search how to kill the president, admits it to the Secret Service, and then allegedly emails the White House with a death threat two months later, the system did not move fast enough. The question now is whether the consequences will.
