Hong Kong activist Samuel Chu: 'I have taken the movement to the White House'

Samuel Chu is one of the last activists of the Hong Kong democracy movement with direct political influence. In the US Congress, his political work has even been so successful that Hong Kong authorities issued an arrest warrant against him based on the National Security Act – the first one ever issued against a US citizen. Chu's new goal: Bringing the Tiananmen artwork "Pillar Of Shame" to Berlin and committing the protest movement to long-term strategies. Fabian Peltsch spoke with Samuel Chu.
