Pam Bondi, the attorney general of the United States, circled the Roosevelt Room in late February, handing out bulky white binders labeled “Epstein Files: Phase 1” to a conclave of Trump-allied influencers summoned to the White House for their first visit.

That Ms. Bondi, the nation’s top law enforcement official, would prioritize a case of importance primarily to conspiracy theorists was telling. Anxious to appease the restive MAGA base, she hyped the disclosure as “breaking news” on Fox the night before, part of an effort to fulfill President Trump’s campaign promise to reveal new details on the financier Jeffrey Epstein’s misdeeds and death.

It was a dud. There were “no bombshells,” she said, according to one of those invited.

Later, activists on the right lashed out at Ms. Bondi. She responded by blaming others, and then dispatched F.B.I. agents and prosecutors from the Justice Department’s national security division to scour the archives, officials familiar with the situation said. They found little. No one knows when Phase 2 is coming. But it is not likely to amount to much, those people said.

Ms. Bondi earned a reputation as a hard-charging prosecutor known for combating opioids and street crime during two terms as Florida attorney general. Since taking office as U.S. attorney general in early February, she has adopted a conspicuously performative approach to survive inside a Trump cabinet that rewards self-promotion, ritualized public flattery and, above all, a willingness to execute White House directives with little fuss.

Over the last few days, Ms. Bondi signed off on Mr. Trump’s acceptance of a luxury Boeing 747-8 plane upgraded to serve as Air Force One donated by the Qatari royal family, which raised a host of ethical and legal questions. As a lobbyist, Ms. Bondi herself received six-figure consulting fees from Qatar.
