I think that still doesn't make Flynn's intentional lies okay and not a crime. You realize because he lied Russia than already had something on him right? And there is the question of why he lied. At best Flynn lied because he thought he was doing something illegal that may not have been.
The FBI and the two agents who intervieewed him in his White House office as National Security Advisor (one of them Peter Strzok, one of them *REDACTED* and undisclosed, Strzok alone makes it suspicious, let alone the second interviewer being undisclosed).
1) The FBI did not disclose to Flynn that he was a suspect of anything or that he could be aggressively pursued for his answers, in a very suspicious meeting, where the FBI/McCabe encouraged Flynn not to include a lawyer. Hillary Clinton in the same situation had NINE lawyers. 2) Even Peter Strzok and the other suspiciously unnamed attorney who interviewed Flynn said in their minutes that Flynn appeared to be very open and not consciously lying or witholding any information, and thus fully cooperative. 3) Undisclosed to Flynn, an illegal FISA warrant based on falsified and misrepresented evidence from the "Steele Dossier" allowed the FBI to listen in on Flynn's perfectly legal conversations with the Russian ambassador, that were essentially a normal establishment of diplomatic relations for the then-incoming Trump administration. So the FBI knew every word in advance of the FBI's Flynn interview that he had said to the Russian ambassador. Legal authority Allan Dershowitz said that it's highly irregular for the FBI to ask questions of someone that they already know the answers to, particularly when he was encouraged not to bring a lawyer. That stinks to high heaven of being a perjury trap, whose only purpose was to entrap Flynn. 4) The "lie" you speak of is likely him being asked "Did you speak to the Russian ambassador about x and y" and Flynn saying "No." And that either Flynn simply forgot that detail was discussed, that the KGB at the FBI alread had a transcript and knew every word of. They never discussed the FISA transcript with Flynn or tried to partly disclose what they knew he had said to refresh his memory, so that Flynn could say "Oh yeah, x and y too, now I remember." No. Its sole purpose was to entrap him on a technicality.
Like everything else about the FBI, DOJ and Mueller investigators, it reeks of political bias and corruption. The corrupt acts to destroy evidence agaainst Hillary and her aides. The corrupt acts to vindictively and selectively manufacture evidence and prosecute Trump and his officials, just to politically bury the Trump administration in false allegations.
How do you get around the fact that all of the Mueller investigators are Democrats, ZERO are Republicans? 9 of the 16 are Democrat campaign donors, at least one of them who donated more than my annual disposable income! Another one (Rhee) who was an attorney immediately prior employed by the Clinton Foundation, squashing FOIA requests for Clinton records, now essentially still protecting Clinton and attacking her political opposition legally from within the Mueller investigation.
To not see the bias and corruption, one has to be a Democrat partisan who would cheer any criminal act that advanced their Bolshevik party.
Liberals who bemoan discrimination, intolerance, restraint of Constitutional freedoms, and promotion of hatred toward various abberant minorities, have absolutely no problem with discriminating against, being intolerant of, restricting Constitutional freedoms of, and directing hate-filled scapegoat rhetoric against conservatives.
EXACTLY what they accuse Republicans/conservatives of doing, is EXACTLY what liberals/Democrats do themselves, to those who oppose their beliefs.
