Hong Kong has postponed legislative elections, citing the pandemic, as it intensifies its crackdown on opposition leaders and critics. A dozen pro-democracy candidates were blocked from running, including prominent activist Joshua Wong. This comes as Hong Kong has issued arrest warrants for at least six pro-democracy figures under its new national security law, including a U.S. citizen, Samuel Chu, who works at the D.C.-based Hong Kong Democracy Council and lives in the United States.
