LOS ANGELES — Federal authorities raided the home and office of Los Angeles Unified School District Superintendent Alberto Carvalho on Wednesday morning, the FBI confirmed.

Law enforcement sources, who requested anonymity because they were not authorized to speak publicly, told the Los Angeles Times that the federal investigation specifically involves Carvalho. However, the precise motivation for the searches at his San Pedro home and LAUSD headquarters was not immediately clear.

FBI agents also searched a residence in Southwest Ranches, a town in Broward County, Fla., in connection with the investigation and have since cleared the scene, according to an FBI spokesman in Miami. Sources told The Times that the property is associated with Carvalho.

The FBI declined to share more information, citing the fact that the affidavits have been sealed by the court. Sources familiar with the probe said that the focus was Carvalho as opposed to the LAUSD, and that it would fall under the broad category of financial issues.

Ciaran McEvoy, a spokesperson for the U.S. attorney’s office in Los Angeles, confirmed Wednesday morning that law enforcement was “executing a judicially approved search warrant” at Carvalho’s home, as well as at the headquarters of LAUSD. He also confirmed a search in Florida, but declined to comment further.

LAUSD officials said in a statement that they had been informed of the law enforcement activity and were cooperating with the investigation. They provided no additional details.

Early Wednesday morning, media swarmed outside of LAUSD headquarters as staff members shuffled in and out of the building. Reporters similarly gathered near 36th and Parker streets, across from Carvalho’s three-bedroom home, as a helicopter hovered above.

Among the small number of curious onlookers were several students from nearby San Pedro High School.

Kyle Ronnholm, 17, said he was in auto shop when he started hearing news about the raid.

“We got curious,” he said. “You don’t wake up on a random Wednesday just thinking I’m going to see my own superintendent being raided by the FBI. It’s pretty crazy.”

He and a few other students walked over and saw three unmarked vehicles and several men wearing jackets with FBI lettering. He said they counted about five federal agents.

Kyle and other students said the agents left shortly thereafter. He and others said they didn’t notice any items being taken from the house.

John Schafer, 62, who lives two doors from Carvalho, said he was at home having coffee with his wife when he heard a siren shortly after 6 a.m. and heard someone commanding residents to stay in their house over a loudspeaker.

“I thought it was some kind of medical emergency,” Schafer said.

He said he looked out his window and saw two cars in the street and a federal agent in tactical gear pointing a rifle toward the superintendent’s house.

Schafer said he didn’t like the way the operation was carried out, given the brandishing of firearms.

“I really think they wanted eyes on this,” he said. “It bugged me.”

Carvalho previously led Miami-Dade County Public Schools before joining LAUSD as superintendent in February 2022. He moved from heading the fourth-largest K-12 public school system in the country to the second-largest.

He came under scrutiny from the Miami-Dade school system’s inspector general in 2020. Carvalho had helped solicit a $1.57-million donation from an online instruction company for a foundation that Carvalho oversees. The company had a contract pending with the district. Once hired, the company provided an online platform that was mired in problems and quickly scrapped, the Miami Herald reported.

In June 2021, the inspector general concluded that the donation, which was meant to benefit teachers, did not violate state or district ethics policies but created “the appearance of impropriety,” and that the foundation, which Carvalho had started, should return the funds. The foundation instead distributed the money in $100 gift certificates to teachers, according to the Miami Herald.

The nature of the federal investigation remains unclear at this point, but Carvalho and other L.A. Unified officials have been outspoken critics of the Trump administration. And L.A. Unified has previously landed on the administration’s list of targets, including this month, when the U.S. Justice Department petitioned to join a lawsuit alleging that L.A. Unified discriminates against white students by providing additional resources to schools with a nonwhite population of 70% or more.

Federal authorities have also probed AllHere, an education technology startup that created a highly touted chatbot for LAUSD several years ago.

Joanna Smith-Griffin, the founder and former chief executive of AllHere, was arrested in 2024 and charged with securities fraud, wire fraud and aggravated identity theft. By then, the chatbot — known as “Ed” — had been withdrawn from service.

Ed was an artificial intelligence tool billed as revolutionary for students’ education and the interaction between LAUSD and the families it serves. The tool was never fully deployed.

“The indictment and the allegations represent, if true, a disturbing and disappointing house of cards that deceived and victimized many across the country,” Carvalho said at the time. “We will continue to assert and protect our rights.”

The indictment and collapse of AllHere was an embarrassment for Carvalho and the school system but did not appear to represent a major financial exposure.

But a former AllHere senior executive has accused the now-collapsed company of inadequate security measures. Even if that is true, there has been no evidence of a related security breach affecting student or employee data.

AllHere also had a contract for somewhat different services with the Miami-Dade County school system, but Carvalho said previously that he had nothing to do with that contract. Carvalho also has denied personal involvement in the selection of AllHere for the AI project in Los Angeles.
