There are at least three issues here. One, Flynn talking to the Russians. No one has made even a colorable case that it was improper.
Two, Flynn apparently not being truthful about it to Pence. I have trouble with this for several reasons. Why was Pence questioning him? Perhaps Flynn wanted to give him plausible deniability. Was Pence overstepping here? Was Pence playing a game he had been put up to by someone?
Three, the leaks. Trump tweeted about this already. A guy who was loyal to Trump and actually pretty important in him getting elected has been disgraced. Trump owes it to him to find out who leaked and destroy them.
He has plenty of weapons. He can bring in Rudy G and turn him loose. A very limited number of people had the intercept information, eg CIA, FBI, Justice and Trump people. CIA and FBI people cannot plead the Fifth(and keep their jobs) and can be forced to take lie detector tests. The journalists who received the leaks can be prosecuted for disclosing secret information. They can be put in front of a grand jury and given immunity. If they won't talk, put them in jail. Put that Yates bitch in front of a grand jury and see if she takes the Fifth. Put her in jail too if she won't talk.
Trump has let his supporters down here and he needs to produce a few bodies to square things. There may come a time when he needs us to go to the streets. We have to trust he has our back.
