How a hacked American nightclub Twitter account was implicated in China's information war

Twitter recently took down a covert network of nearly 1,000 accounts it says are tied to the Chinese government. Many, but not all, of the accounts attacked pro-Democracy protesters in Hong Kong.
Twitter posted a list of all the accounts it had removed along with the tweets the accounts had posted. CNN Business analyzed the accounts and found at least one that stood out: It was targeting America, not protesters. Its name was @LibertyLionNews.
If Twitter is correct and the account is linked to China, it could signal a provocative change in Chinese propaganda targeting the United States, experts say.
