The superintendent of the Los Angeles Unified School District resigned Sunday evening as a federal investigation looms over his tenure leading the second-largest public school district in America.

LAUSD superintendent Alberto Carvalho resigned effective June 21, according to the Los Angeles Times. In his letter, he didn’t directly mention the federal investigation or the FBI raid of his office and home in late February, but alluded to distractions impeding his work. The school district’s board had voted unanimously to place Carvalho on paid leave as superintendent just two days after the February raids.

“Because I believe our schools must remain focused on students and learning without distraction, I am resigning as Superintendent of LAUSD effective today, June 21, 2026,” Carvalho wrote in his resignation letter, reported by the outlet.

“Over the past four years, together, we have made historic progress — gains that belong to our students, our educators, staff and our communities,” Carvalho wrote.

Authorities from the FBI and the U.S. Attorney’s Office for the Central District of California conducted “a search pursuant to an under seal, court-authorized warrant” of Carvalho’s downtown Los Angeles office and his home in San Pedro on Feb. 25, the U.S. Attorney’s office confirmed to the Washington Examiner at the time.

The investigation into Carvalho centered on LAUSD’s contract, under his tenure, with an artificial intelligence model called AllHere, which failed in 2024 just months after it began, according to multiple outlets, including the Los Angeles Times. A consultant for AllHere, Debra Kerr, had her Florida home searched by federal authorities on the same day that Carvalho’s home was raided in February. AllHere’s CEO Joanna Smith-Griffin was arrested and charged with defrauding investors in November 2024.

In a mid-March statement on the raid of his home and office, Carvalho denied any wrongdoing, and his attorneys said that “no evidence has been presented by prosecutors supporting any allegation that Mr. Carvalho violated federal law.”

“Mr. Carvalho remains confident that the evidence will ultimately demonstrate that he acted appropriately and in the best interests of students,” his law firm Holland & Knight said in the statement shared with the outlet.

Carvalho has been in the public spotlight before over his criticism of the Trump administration’s immigration policies. A Portuguese native, he was previously an illegal immigrant before obtaining a student visa, according to the New York Times. Carvalho was the superintendent of Miami-Dade County Public Schools before becoming the LAUSD superintendent in early 2022.
