Clinton: China, if you're listening

Clinton said in her interview with Maddow two nights ago:

"Imagine, Rachel, that you had one of the Democratic nominees for 2020 on your show, and that person said, you know, the only other adversary of ours who is anywhere near as good as the Russians is China.  So, why should Russia have all the fun?  And since Russia is clearly backing Republicans, why don`t we ask China to back us. [...] And not only that, China, if you`re listening, why don`t you get Trump`s tax returns.  I`m sure our media would richly reward you."
