"It’s debatable whether Flynn broke any laws by ..."
If it's debatable, then make the case or shut up. What has it got to do with Hillary's email server and her lies?
There is good evidence Flynn has lied about his contact with the Russian embassy and then went on to mislead Pence. That naturally raises the question of what that contact consisted of and whether any laws were broken. This contact should be seen in the light of the ongoing FBI investigation of the Trump investigation and the allegations of Russian hacking.
We can't know if laws were broken yet because the facts are still not in.. since you believe the claims about election fraud should be investigated fully due to their serious nature I would suppose (?) you would also support an investigation into this question as well.
