I definitely worry about foreign interference. I think it's difficult for us to regulate the kinds of outside information, misinformation and disinformation and the flow of content that is coming into the country. It's hard for us to do that. In many ways, that runs the risk of being way too heavy and undesirable for other reasons, too.
I know I'm repeating myself, but I really think the best way is for people to be informed on their own and to develop those critical skills so that, even if something looks sophisticated, they know the different ways to double-check and triple-check it to make sure they're not being fooled. There's no substitute for that.
For anything the government does, clearly there should be accountability, and in other ways, too. If people are deliberately trying to create instability and disruption in a conversation about who's going to be elected, there needs to be accountability for that, but there are limits to how much the government can do when you really need citizens to be able to recognize misinformation and disinformation themselves.
