WASHINGTON — Decades in the past, the C.I.A. recruited and thoroughly cultivated a midlevel Russian official who started quickly advancing by the governmental ranks. Eventually, American spies struck gold: The longtime supply landed an influential place that got here with entry to the best stage of the Kremlin.
As American officers started to understand that Russia was making an attempt to sabotage the 2016 presidential election, the informant turned one of many C.I.A.’s most necessary — and extremely protected — property. But when intelligence officers revealed the severity of Russia’s election interference with uncommon element later that yr, the information media picked up on particulars in regards to the C.I.A.’s Kremlin sources.
C.I.A. officers fearful about security made the arduous resolution in late 2016 to supply to extract the supply from Russia. The state of affairs grew extra tense when the informant at first refused, citing household considerations — prompting consternation at C.I.A. headquarters and sowing doubts amongst some American counterintelligence officers in regards to the informant’s trustworthiness. But the C.I.A. pressed once more months later after extra media inquiries. This time, the informant agreed.
The transfer introduced to an finish the profession of one of many C.I.A.’s most necessary sources. It additionally successfully blinded American intelligence officers to the view from inside Russia as they sought clues about Kremlin interference within the 2018 midterm elections and subsequent yr’s presidential contest.
CNN first reported the 2017 extraction on Monday. Other details — including the source’s history with the agency and the cascade of doubts set off by the informant’s refusal of the initial exfiltration offer — have not been previously reported. This article is based on interviews in recent months with current and former officials who spoke on the condition that their names not be used discussing classified information.
Officials did not disclose the informant’s identity or new location, both closely held secrets. The person’s life remains in danger, current and former officials said, pointing to Moscow’s attempts last year to assassinate Sergei V. Skripal, a former Russian intelligence official who moved to Britain as part of a high-profile spy exchange in 2010.
The Moscow informant was instrumental to the C.I.A.’s most explosive conclusion about Russia’s interference campaign: that President Vladimir V. Putin ordered and orchestrated it himself. As the American government’s best insight into the thinking of and orders from Mr. Putin, the source was also key to the C.I.A.’s assessment that he affirmatively favored Donald J. Trump’s election and personally ordered the hacking of the Democratic National Committee.
The informant, according to people familiar with the matter, was outside of Mr. Putin’s inner circle, but saw him regularly and had access to high-level Kremlin decision-making — easily making the source one of the agency’s most valuable assets.
Handling and running a Moscow-based informant is extremely difficult because of Mr. Putin’s counterintelligence defenses. The Russians are known to make life miserable for foreign spies, following them constantly and at times roughing them up. Former C.I.A. employees describe the entanglements as “Moscow rules.”
The informant’s information was so delicate, and the need to protect the source’s identity so important, that the C.I.A. director at the time, John O. Brennan, kept information from the operative out of President Barack Obama’s daily brief in 2016. Instead, Mr. Brennan sent separate intelligence reports, many based on the source’s information, in special sealed envelopes to the Oval Office.
The information itself was so important and potentially contentious in 2016 that top C.I.A. officials ordered a full review of the informant’s record, according to people briefed on the matter. Officials reviewed information the source had provided years earlier to ensure that it had proved accurate.
Even though the review passed muster, the source’s rejection of the C.I.A.’s initial offer of exfiltration prompted doubts among some counterintelligence officials. They wondered whether the informant had been turned and had become a double agent, secretly betraying his American handlers. That would almost certainly mean that some of the information the informant provided about the Russian interference campaign or Mr. Putin’s intentions would have been inaccurate.
Some operatives had other reasons to suspect the source could be a double agent, according to two former officials, but they declined to explain further.
Other current and former officials who acknowledged the doubts said they were put to rest when the source agreed to be extracted after the C.I.A. asked a second time.
Leaving behind one’s native country is a weighty decision, said Joseph Augustyn, a former senior C.I.A. officer who once ran the agency’s defector resettlement center. Often, informants have kept their spy work secret from their families.
“It’s a very difficult decision to make, but it is their decision to make,” Mr. Augustyn said. “There have been times when people have not come out when we strongly suggested that they should.”
The decision to extract the informant was driven “in part” because of concerns that Mr. Trump and his administration had mishandled delicate intelligence, CNN reported. But former intelligence officials said there was no public evidence that Mr. Trump directly endangered the source, and other current American officials insisted that media scrutiny of the agency’s sources alone was the impetus for the extraction.
Mr. Trump was first briefed on the intelligence about Russian interference, including material from the prized informant, two weeks before his inauguration. A C.I.A. spokeswoman responding to the CNN report called the assertion that Mr. Trump’s handling of intelligence drove the reported extraction “misguided speculation.”
Some former intelligence officials said the president’s closed-door meetings with Mr. Putin and other Russian officials, along with Twitter posts about delicate intelligence matters, have sown concern among overseas sources.
“We have a president who, unlike any other president in modern history, is willing to use sensitive, classified intelligence however he sees fit,” said Steven L. Hall, a former C.I.A. official who led the agency’s Russia operations. “He does it in front of our adversaries. He does it by tweet. We are in uncharted waters.”
But the government had indicated that the source existed long before Mr. Trump took office, first in formally accusing Russia of interference in October 2016 and then when intelligence officials declassified parts of their assessment about the interference campaign for public release in January 2017. News agencies, including NBC, began reporting around that time about Mr. Putin’s involvement in the election sabotage and on the C.I.A.’s possible sources for the assessment.
The following month, The Washington Post reported that the C.I.A.’s conclusions relied on “sourcing deep inside the Russian government.” And The New York Times later published articles disclosing details about the source.
The news reporting in the spring and summer of 2017 convinced United States government officials that they had to update and revive their extraction plan, according to people familiar the matter.
The extraction ensured the informant was in a safer position and rewarded for a long career in service to the United States. But it came at a great cost: It left the C.I.A. struggling to understand what was going on inside the highest ranks of the Kremlin.
The agency has long struggled to recruit sources close to Mr. Putin, a former intelligence officer himself wary of C.I.A. operations. He confides in only a small group of people and has rigorous operational security, eschewing electronic communications.
James R. Clapper Jr., the former director of national intelligence who left office at the end of the Obama administration, said he had no knowledge of the decision to conduct an extraction. But, he said, there was little doubt that revelations about the extraction were “going to make recruiting assets in Russia even more difficult than it already is.”
