Yes, who was? (Hint: not the CIA)
You’re talking about Victoria Nuland, who was assistant Secretary of State at the time. She visited the protests at the time her boss was decrying the treatment of protesters and openly voiced support for democracy as opposed to how Yanukovich’s government was treating them. She helped distribute food – the cookies claim is a tell that you spend a lot of time consuming Russian propaganda since they’ve tried to spin this as America wanting compliant Ukrainian lapdogs - but that’s hardly a secret: all of this was in public in her official capacity, hardly some shadowy CIA plot.
