In Sen. Klobuchar's questioning, Mudge quotes a conversation he'd had with Parag Agrawal regarding a request by Vladimir Putin to censor and surveil Russian Twitter users: "we don't really have the ability and tools to do things correctly, this is a lot of work, it's not really driving our main executive incentive goals, is there a way that we can simply punt? And since they have elections, doesn't this make them a democracy?"
That specific Q&A exchange begins at 1:00:15.
The immediate prior exchange with Sen. See is also telling. "I'm reminded of one conversation with an executive, when I said, 'I am confident we have a foreign agent', and their response was 'Well, since we already have one, what does it matter if we have more? Let's keep growing the office.'"
For those who haven't listened to the testimony, I strongly recommend doing so --- it's informative, level-headed, and reasonably fast-paced.
