Maybe I can answer this question. Thank you.
First of all, I'm going to start by saying that foreign interference does not occur only during an election. Foreign interference occurs all the time, every day, and I think we have to bear that in mind, because when you start to look at an election, which is a finite time frame, you're not going to always catch the foreign interference that's happening at that point. We start watching what's happening every day with regard to the buildup to an election, and we are constantly monitoring to see if there is any type of foreign interference coming from a hostile state actor.
When you're looking at a specific time frame and you're dealing with perhaps a social media attack, it takes a very long time to be able to figure out where that actually came from. You don't just flip a switch and already get it back to the country it came from or the threat actor it came from. It takes a long time for the intelligence services to put that work together and to follow that train back.
Also, when you're looking at social media, we do not monitor social media. You don't want your national intelligence service to monitor all social media. We have to make sure that we know there's a threat there, and then it comes under our mandate.
