Various outlets are reporting that former national security advisor Michael Flynn is offering, through his attorney, to be interviewed by House and Senate intelligence committees in exchange for a grant of immunity from criminal prosecution.
Flynn’s attorney, Robert Kelner, has couched it as a request for immunity from “unfair prosecution”, but it is fairly safe to assume that the request for immunity is motivated by the belief that he may have committed a crime.
If Flynn did in fact discuss potentially lifting sanctions against Russia prior to the time that Trump took office, his conduct would have constituted a violation of federal law, which prohibits civilians from interfering in the foreign policy of the United States.
You may recall that Flynn initially denied having any such conversation, then later claimed he didn’t remember but couldn’t say whether or not sanctions had been discussed.
It appears he may be getting his memory back.
