Attorney General Pam Bondi signaled on Thursday that there was unlikely to be a criminal investigation into the sharing of military operation details in an unsecured text group, declaring that the specifics of when fighter jets would depart and when bombs would fall were “not classified.”

Ms. Bondi, speaking at a news conference in Virginia, was asked about the public debate surrounding Defense Secretary Pete Hegseth after he sent details of a coming attack on rebels in Yemen to senior administration officials in a Signal group chat that accidentally included a magazine editor.

“It was sensitive information, not classified, and inadvertently released,” Ms. Bondi said, while praising the military operation that ensued.

“What we should be talking about is, it was a very successful mission,” she said, before quickly accusing Democrats from previous administrations of mishandling classified information.

“If you want to talk about classified information, talk about what was in Hillary Clinton’s home,” she said. “Talk about the classified documents in Joe Biden’s garage, that Hunter Biden had access to.”

The Justice Department opened investigations into Mrs. Clinton and Mr. Biden in those instances, but neither ultimately faced criminal charges. She did not mention the prosecution of Mr. Trump over his handling of classified documents after his first term in office — a case which was ultimately abandoned when he won a second term.
