There were two failings in our system. One was that we don't require influencers, just as you don't, to disclose when they're being paid to do political content. Also, the Foreign Agents Registration Act is extremely poorly enforced in the United States. The two individuals—Canadians, as it were—who were in charge of Tenet Media also did not disclose their connection, even though they knew they were working for the Russians. There are two problems there.
I have mixed feelings that we don't have time to get into about foreign agents-related legislation and whether it works or not, but here, again, encouraging them to know their customer would have at least said to these influencers, “Okay, you've been presented this very suspicious-looking CV from a man named Edward Gregorian, who has no online footprint. Perhaps you should do a little bit more digging.”
If it is incumbent on them to report that sort of thing, I think it's possible. These aren't dumb individuals; their spidey sense would have gone off and they should have said, “Perhaps I shouldn't take this $100,000 per YouTube video, because this guy doesn't seem totally legit.” That's the behaviour you want to encourage, and putting that on each individual influencer hopefully will encourage some more of that transparency.
You could also, as I understand it, look at expanding your foreign agents registration and, importantly, as we do not do this in the United States, actually make sure that those laws are enforced.
