The superintendent of America's second-largest school district resigned Sunday — four months after FBI agents raided his home with long rifles, handcuffed him, and hauled away his cellphones and computers — and parents still don't know where their tax dollars went.

Alberto Carvalho ran the Los Angeles Unified School District, a bureaucracy commanding billions in public money, at a salary of $440,000. He had been on paid leave since February 27, when the school board voted 7-0 to sideline him after the FBI executed search warrants at his $2.5 million San Pedro residence, LAUSD headquarters, and a third location near Miami. His resignation, effective immediately, was conveyed in a letter first reported by the Los Angeles Times. He wrote that he didn't want to become a "distraction" and that "placing students first has always guided my work." He made no mention of the FBI investigation.

Here's what the public knows: In 2024, Carvalho personally touted a deal with AllHere, an education technology company that built an AI chatbot named "Ed" for the district. He called it "a game changer." LAUSD paid the company $3 million. Less than three months later, the district dropped AllHere. The company collapsed into bankruptcy. Months after that, founder Joanna Smith-Griffin was charged with securities fraud, wire fraud, and identity theft. The FBI's Miami raid targeted the home of Debra Kerr, a salesperson whose clients included AllHere, according to the Miami Herald. Carvalho later denied personal involvement in selecting AllHere.

But the outlets can't agree on what the FBI is actually investigating. CBS News reported that a source with direct knowledge said the probe predates the Trump administration and involves alleged kickbacks Carvalho may have received while still running Miami-Dade County Public Schools — not his LAUSD work. The New York Times, by contrast, framed the investigation as connected to "the district's dealings with an A.I. start-up," tying it directly to LAUSD. The underlying affidavit remains under seal, and the FBI won't comment.

Carvalho has not been charged. His attorneys issued a statement in March saying he "has always acted in the best interests of students and within the bounds of the law" and that "no evidence has been presented by prosecutors supporting any allegation that Mr. Carvalho violated federal law."

The establishment press is content to let this man ride off with a polite resignation letter. Whether the FBI's interest traces back to Miami or straight to LAUSD, the money trail runs through public funds — taxpayer dollars meant for students. A $3 million contract to a now-bankrupt AI company whose founder faces federal fraud charges. A superintendent who publicly championed that deal. A Florida salesperson caught up in the same dragnet. And a school district that scrubbed its headquarters while agents searched it.

Carvalho's spokesman says he respects the rule of law. Good. Then let's see the rule of law work. Parents in Los Angeles — and every American footing the bill for public education — deserve to know what the FBI found in those cellphones and paper documents, and whether the man who controlled their children's schools was on the take.

The affidavit is still sealed. The superintendent is gone. The money is gone. And nobody in power is answering the question.
