The House Intelligence Committee is seeking information about a Yahoo News report that CIA officials plotted to kidnap Julian Assange from the Ecuadorean Embassy in London in 2017 after WikiLeaks published documents describing the spy agency’s hacking tools.

“We are seeking information about it now,” said Democratic Rep. Adam Schiff, the committee chairman, in an interview on the Yahoo News “Skullduggery” podcast.

Schiff added that, as the ranking Democrat on the intelligence panel in 2017, he was never briefed about the CIA’s plans to target Assange. But he said the committee had reached out “to the agencies” — an apparent reference to the CIA and the Office of the Director of National Intelligence (ODNI) — after reading about the Yahoo News account describing deep divisions within the Trump administration, including objections from White House lawyers, over the CIA’s plans for unusually aggressive measures to cripple WikiLeaks that had been proposed by then agency Director Mike Pompeo.

Asked if he had received any response to the committee’s inquiry, Schiff replied: “I can’t comment on what we’ve heard back yet.” (Spokespeople for the CIA and ODNI declined comment.)

The disclosure by Schiff that the committee is pursuing information about the CIA’s measures targeting WikiLeaks comes the day after the ACLU and more than 20 otherhuman rights and press freedom groups wrote to Attorney General Merrick Garland urging him to drop the criminal prosecution of Assange in light of what they called “shocking” reporting by Yahoo News “on the government’s conduct in this case.”

It also comes on the eve of a critical hearing before a British appellate court in London next week over the U.S. Justice Department’s appeal of a lower court judge’s ruling rejecting its request to extradite Assange to the United States to face trial for publishing classified documents in violation of the World War I-era Espionage Act. The judge concluded that Assange, who is now in a British prison after spending years holed up in the Ecuadorean Embassy in London, would be at serious risk of suicide if he were incarcerated in an American prison.

But lawyers for Assange intend to raise the issue of what they view as the CIA’s misconduct, arguing that returning him to a country where some top officials once plotted to kidnap him strengthens the judge’s conclusions about the risk of suicide and should be an additional basis for turning down the U.S. extradition request.
