Re: A quiet refrain
Let's limit the emphasis here:
"The United States Of America [ ... ] regulates the activities of foreign individuals and entities in and affecting the United States in order to prevent, disclose, and counteract improper foreign influence on U.S. elections and on the U.S. political system."
They may be affecting the US but they're not in it. For your argument to succeed that needs to be an or. I think I've found your bug.
"Tell your boss at the Internet Research Agency to change the script. You are much more transparent than you think you are."
Perhaps I should point out that I'm a Brit with quite a bit of experience in the witness box, called by the Crown (i.e. prosecution), back in the day. I'm a strong believer in due process of law and not at all convinced territorial over-reach is due process.
