Worth noting that these foreign accounts are pretty small. The biggest foreign pro-MAGA account mentioned in the article is "MAGA NATION" with ~400k subs, with the others being in the 10k-100k subs range.
Contrast that with legit pro-rightwing accounts: @tuckercarlson (17M), @benshapiro (8M), @RealCandaceO (7.5M), @jordanbpeterson (6M), @catturd2 (4M), @libsoftiktok (4.5M), @seanhannity (7M).
Color me shocked that libsoftiktok is an actual US account. I was certain it was a foreign operative
Guessing you don't follow politics much? The owner of that account is an American woman, her identity actually leaked years ago. She's sat for several in-person interviews, I think.
