Even if contacts occurred during the transition period after the election -- the contacts are legal and expected from the Trump organization. For example, how many foreign leaders did Trump (or Obama or other Presidents earlier) have calls with to congratulate him while also talking key policy issues during the transition period. Flynn contacting the Russians at the request of Trump to talk about ISIS and other concerns. -- totally expected and normal. Flynn got in trouble for lying to the FBI about the dates/times of the contacts -- nothing more.
