...because those are the ones she filed recounts in?
Trump or his campaign is free to do that if they want.
I don't know why people keep bringing this up. Jill Stein obviously isn't a neutral player in this, and, as somebody said, if miraculously somehow the election was flipped she'd be regarded as a hero. There's no heroism for her for doing it in states where Trump barely lost.
But someone else can try to do recounts in those states. Its not like they can't do it. So I donno why people keep bringing this up as if they can't.
