"The comments appear contradict the impression given by Trump on Friday aboard Air Force One that he was not familiar with a Washington Post report that revealed that Flynn had not told the truth about the calls."
What's that line in "The Rock" after time ran out to launch a chemical weapon from Alcatraz?  "Either we look like liars or incompetent?"  Either way it is, there is no excuse for Trump not being on top of this for at least the last couple of weeks.  This is only compounded by his concerted attempt to undermine trust in the news when he appoints people with trust issues ("Flynn Facts" ring any bells?) as an official in our national security.
This is based upon applying Hanlon's razor that this was mere neglect and not something more conspiratorial.
Then there's the attempt to deflect attention from Trump's incompetence/lying by trying to put "leaks" in the limelight as if whistleblowers aren't protected for just such an occasion.
