The US extracted a high-level spy from inside Russia in 2017, reports say.
Citing “multiple Trump administration officials with direct knowledge” of the operation, CNN reported that US intelligence feared the source’s cover could be blown by US officials.
The decision was made soon after a meeting in which President Trump unexpectedly shared classified US intelligence with Russian officials.
Reports said the mole was the highest-level US source inside Russia.
Reporting by CNN and the New York Times said the source was outside the inner circle of Russian leader President Putin but had regular access to Mr Putin and was even able to photograph documents on the leader’s desk.
The covert source reportedly spied for the US for more than a decade as they rose through the ranks of the Russian government. According to the New York Times, the source was instrumental in the conclusion by US intelligence agencies in 2016 that Mr Putin had personally orchestrated Russia’s interference in the US presidential election.
The source’s information was so sensitive that then-CIA director John Brennan prepared special sealed files for President Obama, rather than include it in the president’s ordinary briefing, the Times report said.
The CIA – the intelligence agency said to have run the mole – declined to comment on the apparent revelations. White House press secretary Stephanie Grisham said CNN’s reporting was “not only incorrect” but had “the potential to put lives in danger”.
