Mueller's office has responded to claims by Gen. Flynn's lawyers that the FBI might have tricked him into lying to them. Basically, prosecutors say that by the time agents talked to him, he'd been lying to everybody for two weeks. 
Mueller's office says that Flynn, then the national security officer and a retired general, "does not need to be warned it is a crime to lie to federal agents to know the importance of telling them the truth."
And Mueller's office says Flynn continued lying to DOJ after his White House interview. He "made those false statements while represented by counsel and after receiving an explicit warning that providing false information was a federal offense."
Mueller's office says Flynn actually seemed to be pretty good at lying.
And prosecutors say his lies raise "the question of why he was lying to the FBI, the Vice President, and others."
And prosecutors say his lies raise "the question of why he was lying to the FBI, the Vice President, and others."
(They don't answer that question, but in an earlier filing, the special counsel's office redacted a great deal of information about the extent of Flynn's cooperation.)
Seems like Gen. Flynn told McCabe that the FBI probably already knew what he had said to the Russian ambassador (then shortly thereafter lied about it to two FBI agents).
Flynn gave the FBI agents who came to interview him "a little tour" of the area around his White House office. While he was doing that, President Trump walked right through the middle of the group "but nobody paid any attention to the agents."
Flynn talked to the agents about the "President's knack for interior design." He went on for so long that one of them, "Strzok wondered if the National Security Adviser did not have more important things to do."
At the time of the interview, both Strzok and other FBI agent who was present "had the impression at the time that Flynn was not lying or did not think he was lying."
Note that this isn't from the FBI's 302 of it's interview with Flynn. It's the report of an interview a prosecutor and an FBI supervisor conducted with Strzok in July 2017 "to collect certain information regarding Strzok's involvement in various aspects" of Mueller's probe.
Here's the filing, thanks to @big_cases ->
