Three pro-democracy lawmakers were ejected from Hong Kong's legislative chamber Thursday morning, disrupting the second day of debate on a contentious bill that would criminalize insulting or abusing the Chinese national anthem. The legislature's president, Andrew Leung, suspended the meeting minutes after it began and ejected Eddie Chu for holding up a sarcastic sign about a pro-Beijing lawmaker that read "Best Chairperson, Starry Lee."A second pro-democracy lawmaker was ejected for yelling after the meeting resumed, and then a third after rushing forward with a large plastic bottle in a cloth bag that spilled its brownish contents on the floor in front of the president's raised dais. The third lawmaker, Ted Hui, later described the contents as a rotten plant, and said he wanted Leung to feel and smell the rotting of Hong Kong's civilization and rule of law, and of the "one country, two systems" framework that democracy activists feel is under attack by China's ruling Communist Party. "We have wanted to use any method to stop this national anthem law getting passed by this legislature, which is basically controlled by the Chinese Communist Party, because the law is just another way of putting pressure on Hong Kong people," Chu said outside the chamber.

(Vincent Yu/The Associated Press) In Beijing, China's national legislature was set to ratify a proposal later Thursday to impose a national security law on Hong Kong, a Chinese territory that is supposed to have a high degree of autonomy under a "one-country, two systems" framework. The city's pro-democracy opposition sees both the security legislation and the anthem law as assaults on that autonomy, and the U.S. has called on China to back off on the security law. U.S. Secretary of State Mike Pompeo notified Congress on Wednesday that the Trump administration no longer regards Hong Kong as autonomous from mainland China, setting the stage for the possible withdrawal of the preferential trade and financial status the U.S. accords the former British colony. China blocked a U.N. Security Council meeting to discuss the legislation Wednesday, with China's U.N. Ambassador Zhang Jun tweeting that Hong Kong is "purely China's internal affairs." Chinese foreign ministry spokesperson Zhao Lijian said ahead of Pompeo's announcement that China would take necessary steps to fight back against any "erroneous foreign interference in Hong Kong's affairs."
