Can someone give me an overview on the Jill Stein situation?

I have never heard of Jill Stein until just a few months ago when I saw some article about her on the Lemmy homepage. Then I saw more and more articles about her. However, I don't really know why the media is paying so much attention to her. She is just a third party candidate, right? There are other third party candidates that aren't constantly popping up in the news. So why Jill Stein? I hear its something to do with Russia and a general sense of her goal being to take votes away from Kamala.
