Deploying National Guard troops to LA: A challenge to federalism?

On June 8, President Donald Trump deployed National Guard troops to Los Angeles without a formal request from California Governor Gavin Newsom. This raises serious questions about the balance of power between state and federal governments. Is this a violation of America's federalist principles? Andy Mok, senior research fellow at the Center for China and Globalization, speaks with CGTN's Wang Guan, arguing that while the move is legally within the president's authority, it signals a strategic push toward centralizing power, potentially eroding the traditional framework of U.S. federalism. What's your take? Is this a necessary show of strength or a dangerous precedent?
