Security Secretary Tang lashes out at journalist association In an interview with Ta Kung Pao, Secretary for Security Chris Tang said that fake news, bogus reporters and independent media outlets had caused hatred of authorities among youths since the protests in 2019.

Association chairman Ronson Chan took issue with Tang's statement that the Association had "positions filled by many student journalists", which he called "factually wrong" as only 13 per cent of the executive committee were students. He also said that while "everyone can be a journalist" was not something the Association advocated, it was a concept safeguarded under the Basic Law.
