A 26-year-old Ohio man with a documented history of mental illness and prior run-ins with the law pleaded guilty to federal charges for smashing historic windows at Vice President JD Vance's Cincinnati residence, an attack prosecutors say caused $28,000 in damage.

William DeFoor entered his guilty plea during a Tuesday court hearing on two federal counts: causing willful injury or depredation and carrying out physical violence against government officials. The charges stem from a January 5 incident in which DeFoor, armed with a hammer, breached the property line at Vance's Cincinnati home, smashed the window of an unmarked Secret Service vehicle, and then turned the hammer on the residence itself, destroying what prosecutors described as "historic glass windows." He now faces up to 30 years in federal prison.

Vance and his family were not at the Cincinnati property at the time. The Vances moved to the vice president's official residence at the Naval Observatory in Washington, D.C., roughly two and a half miles from the White House, after President Trump's 2024 election victory. But the attack on a sitting vice president's home, carried out against the orders of armed federal agents, raises hard questions about how a man already known to the courts for violent and erratic behavior was free to act in the first place.

Secret Service agents ordered DeFoor to stop, he kept swinging

The sequence of events on January 5, as described by federal prosecutors, left little ambiguity. DeFoor arrived at Vance's Cincinnati residence during the early night hours. Secret Service agents on site caught him crossing the property line and smashing the window of an unmarked law enforcement vehicle. They ordered him to drop the hammer and stop.

He ignored them.

DeFoor then moved to the residence itself and began destroying historic glass windows on the property. When agents moved to apprehend him, he attempted to flee on foot. The Secret Service caught him. The Justice Department later estimated the damage to the windows alone at $28,000.

U.S. Attorney Dominick Gerace II framed the prosecution in broad terms, telling the New York Post:

"Acts of violence directed against our political leaders, their families, or property, have no place in our society and will not be tolerated."

Gerace added that elected officials "at all levels of government, must be permitted to carry out their duties free from threats, vandalism, and other forms of violence," and pledged that perpetrators like DeFoor who put that freedom at risk through "violent, destructive actions" would be "vigorously prosecuted."

Vice President Vance, who has maintained a busy public schedule throughout his time in office, has not publicly commented on the guilty plea. The New York Post reached out to Vance's office for comment but did not report receiving a response.

DeFoor's rap sheet includes a prior competency ruling and court-ordered treatment

The January 5 attack was not DeFoor's first encounter with the justice system, and his prior record makes the timeline harder to explain away. Before the Vance incident, DeFoor had received a two-year mandatory health treatment sentence for vandalizing an interior design company. He had also been charged with trespassing at UC Health's psychiatric and emergency services facility in Cincinnati.

In one of those earlier cases, a judge found DeFoor not mentally competent to stand trial. He has a documented schizophrenia diagnosis.

His mother, Catherine DeFoor, issued a statement acknowledging her son's illness.

"Mental illness is a terrible thing. It is a struggle which can take over the life of a beautiful person."

She added: "Unfortunately, for our child, it has taken over his life in a way that we never could have imagined."

The family is not without means. DeFoor's father, William DeFoor Sr., is a Harvard University graduate, a pediatric urologist in Cincinnati, and a professor at the University of Cincinnati's College of Medicine. The elder DeFoor lives in a $1.3 million home in Cincinnati's upscale Hyde Park neighborhood. He also donated thousands of dollars to Kamala Harris's failed 2024 presidential campaign.

None of that wealth or professional standing prevented a young man with a known psychiatric history and a prior finding of incompetence from ending up on the vice president's property with a hammer in his hand. Vance, whose willingness to court controversy has made him a frequent target of political opponents, now finds his own home the site of a federal crime.

A system that saw the warning signs and still missed the threat

DeFoor reportedly goes by "Julia" on social media and has been described as the son of a prominent Ohio millionaire family. But the most relevant details in his background are not about identity or wealth. They are about a pattern the courts had already documented: a man with schizophrenia, a history of property destruction, a prior competency finding, and a mandatory treatment sentence, who was nonetheless free and unsupervised enough to breach Secret Service security at the home of the vice president of the United States.

The federal charges DeFoor pleaded guilty to carry a combined maximum sentence of 30 years. No sentencing date has been publicly reported. It remains unclear whether additional charges were considered and dropped as part of a plea agreement, or whether the $28,000 damage estimate covers only the residential windows or also includes the unmarked law enforcement vehicle DeFoor smashed.

Vance has faced no shortage of political headwinds in office, from questions about his 2028 prospects to the kind of scrutiny that comes with a high national profile. But a hammer attack on a vice president's home is not politics. It is a federal crime, one that a functioning mental health and criminal justice system should have been positioned to prevent.

The Vance family was fortunate not to have been home that night. DeFoor's guilty plea ensures some measure of accountability. But the fact that a man previously found incompetent to stand trial could walk up to a vice president's residence with a hammer, and keep swinging after federal agents told him to stop, is a failure that a courtroom plea does not fully answer.

Accountability for DeFoor is welcome. The harder question is who accounts for the system that let him get there.
