Well, there's a bipartisan bill that threatens to abolish HK's treatment as separate from mainland China for trade purposes, if HK's autonomy becomes insufficient.
(And, I despise Ted Cruz, but kudos for supporting that bill.)

China Daily is trying to almost completely misrepresent the reason for the protests. The only way they could make it more "opposite day" is by calling the protest a celebration festival for the love of Chinese authority in Hong Kong.
The funny thing about the misrepresentation is that the U.S. isn't really even meddling. We care our trade deficit with China and tariffs than human rights abuses in China.
