There's no question that we've seen this in U.S. presidential campaigns and other campaigns. Bots are created for the explicit purpose of getting people riled up. Sometimes they'll do both sides; they'll do the left and the right. The reason is that they want to sow discord in the United States. You can probably think of what countries are doing this.
I want to mention technology—because it was mentioned before—and where the risks are. The American military tried an e-voting project where soldiers who were posted overseas could actually e-vote. I was asked to comment on the security of the system. It was great. You had to do a video selfie of yourself, and you really proved who you were. However, some of those soldiers had cellphones that were made by Huawei, Xiaomi, Meizu. Here you had the end point, the cellphone, that could be vulnerable. It's the weakest link theory. That could be the way in which the e-voting system might have been corrupted.
