WASHINGTON — Newly discovered emails found on a computer seized during an investigation of disgraced former Rep. Anthony Weiner have prompted the FBI to make new inquiries related to Hillary Clinton’s private email server, according to three people familiar with the deliberations.

FBI Director James B. Comey informed congressional leaders Friday that the agency would take “appropriate investigative steps” to determine whether the newly discovered emails contain classified information and to assess their importance to the Clinton server probe.

The emails were found on a computer used jointly by both Weiner and his wife, top Clinton aide Huma Adebin, according to a person with knowledge of the inquiry. Federal officials have been examining Weiner’s alleged sexually suggestive online messages with a teenage girl. The link to the Weiner probe was first reported by the New York Times.

Comey’s announcement appears to restart the FBI’s probe of Clinton’s server, which previously ended in July with no charges. The explosive announcement, coming less than two weeks before the presidential election, could reshape a campaign that Clinton, the Democratic nominee, has been leading in public polls.

In a brief letter to congressional leaders, Comey said that the FBI, in connection with an “unrelated case,” had recently “learned of the existence of emails that appear to be pertinent to the Clinton investigation.”

Comey wrote that he had been briefed on the new material Thursday. “I agreed that the FBI should take appropriate investigative steps designed to allow investigators to review these emails to determine whether they contain classified information, as well as to assess their importance to our investigation,” he wrote.

An FBI spokesman on Friday declined to elaborate, and a spokesman for Attorney General Loretta E. Lynch declined to comment.

Clinton campaign chairman John Podesta called it “extraordinary that we would see something like this just 11 days out from a presidential election” and called on Comey to provide a fuller explanation.

He noted that Comey, in July, had said that “no reasonable prosecutor” would bring such a case. And he said the campaign was “confident this will not produce any conclusions different from the one the FBI reached in July.”

Comey provided no details about the unrelated case that resulted in the finding of the new emails. A law enforcement official, speaking on condition of anonymity, said the emails were “numerous.”

The official said once informed of the find, Comey felt an obligation to inform Congress, since he had previously told lawmakers the investigation had been completed. As a technical matter, however, the Clinton investigation was never formally closed, the official said.

Abedin, who has worked for Clinton since the 1990s, is vice-chairman of Clinton’s presidential campaign. She exchanged thousands of emails with Clinton while serving as her deputy chief of staff at the State Department. She, like Clinton, used an email address routed through the private server. She announced in August that she was separating from Weiner following a report in the New York Post about a Weiner sexting incident.

When he announced the FBI’s findings in July, Comey said that Clinton had been “extremely careless” in her handling of classified material, which had been found among the emails exchanged on her private server.

He had said that his investigators found evidence of potential violation of laws governing the handling of classified information.

In particular, he said investigators did not find evidence that there had been intentional mishandling of classified material or indications of disloyalty to the U.S. or efforts to obstruct justice.

Comey had come under enormous pressure from Republicans for his recommendation to bring no case against Clinton. Republican presidential candidate Donald Trump has repeatedly cited the decision as a sign of corruption endemic to Washington institutions and promised that, if elected, he would reopen the investigation.

Podesta on Friday cited the political pressure on Comey in questioning the director’s actions, saying that Republicans had been “browbeating” career FBI officials “to revisit their conclusion in a desperate attempt to harm Hillary Clinton’s presidential campaign.”

Trump, addressing supporters in New Hampshire Friday, hailed the FBI’s announcement – saying he had “great respect” for the agency’s decision to “right the horrible mistake that they made.”

“Perhaps, finally, justice will be done,” he said, as the crowd pumped fists and cheered, “Lock her up! Lock her up!”

As the news broke, the Dow Jones industrial average dropped more than 150 points.

Word also began to spread quickly on Capitol Hill, where lawmakers saw the announcement as a potential game-changer for the election.

“A total bombshell,” said Rep. Peter T. King (R-N.Y.), member of the House Homeland Security Committee. King predicted the FBI would not close its inquiry prior to the election, and said he believed Comey wanted the public to know of his move regardless of the outcome.

“He wants it all out there,” King said.

WikiLeaks has been releasing emails hacked from the account of campaign chairman John Podesta in recent days, including material in which some of Clinton’s closest advisors expressed surprise over her use of the server.

“[D]id you have any idea of the depth of this story?” Podesta asked campaign manager Robbie Mook late on March 2, 2015, the day the New York Times revealed Clinton had exclusively used a private account as secretary.

“Nope,” Mook replied early the next day. “We brought up the existence of emails in [research] this summer but were told that everything was taken care of.”

The State Department’s deputy spokesman, Mark Toner, said the FBI has not notified them of the new emails and referred all questions to the FBI.

“We stand ready to cooperate if we’re asked to do so,” he told reporters. “But I don’t have any additional details at this point.”
