From the article:

Newly released documents indicate former FBI Director James Comey kept his superior at the Justice Department in the dark about the bureau's investigation into retired Lt. Gen. Michael Flynn.

Former Deputy Attorney General Sally Yates told special counsel Robert Mueller’s team that she first learned the FBI possessed and was investigating recordings of Flynn’s late 2016 conversations with a Russian envoy following a Jan. 5, 2017, national security meeting at the White House. It wasn't Comey who told her, but former President Barack Obama.

Yates, who was briefly the acting attorney general during the early days of the Trump administration before getting fired, also laid out how in the ensuing days, Comey kept the FBI's actions cloaked in secrecy and repeatedly rebuffed her suggestions that the incoming Trump team be made aware of the Flynn recordings.

Yates told Mueller’s team she first learned of the Flynn recordings following a White House meeting about the Intelligence Community Assessment attended by Yates, Comey, Vice President Joe Biden, then-CIA Director John Brennan, then-Director of National Intelligence James Clapper, then-national security adviser Susan Rice, and others. Obama asked Yates and Comey to stay behind when the meeting concluded.

Obama “started by saying that he had ‘learned of the information about Flynn’ and his conversation with Russian ambassador Sergey Kislyak," Yates said, according to the notes. “Obama specified he did not want any additional information on the matter but was seeking information on whether the White House should be treating Flynn any differently.”

Yates told investigators that “at that point,” she “had no idea what the President was talking about.” She “recalled Comey mentioning the Logan Act” but could not remember if Comey specifically said there was an “investigation.”

"It was not clear ... where the President first received the information," Yates said, adding that she “did not recall Comey’s response to the President’s question about how to treat Flynn.” Yates told Mueller's team, “She was so surprised by the information she was hearing that she was having a hard time processing it and listening to the conversation at the same time," the notes said.
