Trump could have easily, and quietly, announced support behind his intelligence agencies to look into possible Russian interference. His announcement could have been something as simple as "Although there were no successful attempts to alter the the 2016 Presidential election, there were attempts. I believe it is important to protect democracy that we evaluate the attempts and ensure that we are in a position to successfully defend our system again in future elections."
