Someone showed candidate Trump how they can hack American elections, they told him it would look like hacking in favor of Hillary C. He could make a big deal about it when he lost the election. 
Except he won anyway. But he still has this hot info, if he could just roll it so it backs up what he said before voting day. 
But its a double mcguffin, reverse psychology, see?  He should have let that drop off the radar, but he feels smug and wants to use this nugget to issue more executive orders than any previous president. Its a prediction based on body language and his choice of words on the topic. He had a chance to better but chose reductive action so far
