Well your understanding is wrong. That's why you shouldn't get all your info from Fox News. Here's a Wall Street Journal article detailing how Flynn was seeking a "grant of immunity" from prosecution from the FBI, the House and Senate intel committees, in exchange for his testimony. There might very well have been a crime committed with regards to NSA "leaking" but don't change the subject. You asked "what evidence is there that Flynn broke the law" and I laid it out for you.....You still going to deny that Flynn committed a crime(s)?
