NEW YORK — The FBI was trying to get a look at thousands of Hillary Clinton’s emails on disgraced former congressman Anthony Weiner’s computer partly to see if anyone had hacked in to steal classified information, according to court documents unsealed Tuesday.

Investigating possible hacking appeared to be a secondary rationale for the email search, which FBI Director James Comey launched in the waning days of the presidential election.

When the FBI asked a magistrate judge in New York to issue a search warrant for Weiner’s computer on Oct. 30, an agent spent pages describing concerns it might contain evidence Clinton had mishandled classified information.

The warrant application, made public Tuesday, was filed two days after Comey informed Congress investigators had discovered email correspondence that could be pertinent to his recently closed probe of Clinton’s use of a private email server while she was secretary of state.

In the document, the agent wrote that thousands of emails between Clinton and top aide Huma Abedin had been discovered on a laptop used by Weiner, Abedin’s estranged husband.

At the time, investigators had yet to look at the content of those emails, but based on previous work in the case the agent wrote they had reason to suspect they might contain classified material, possibly including top-secret information that could cause “grave damage to national security” if disclosed.

“A complete forensic analysis and review,” the agent added, “will also allow the FBI to determine if there is any evidence of computer intrusions into the subject laptop, and to determine if classified information was accessed by unauthorized users or transferred to any other unauthorized systems.”

A magistrate judge signed off on the search warrant that day.

The FBI hasn’t publicly revealed whether it found any evidence of a hacking attempt.

During the presidential campaign, hackers accessed the email accounts of Democratic Party officials and Clinton’s campaign chief, John Podesta, and leaked them to the anti-secrecy website WikiLeaks.
