"To those who think they can overturn the United States Constitution, know this: You will never win," says Arnold Schwarzenegger, the former Republican governor of California, actor and bodybuilder, in a video posted to Twitter. Schwarzenegger condemns US President Donald Trump -- "the worst president ever" -- and his enablers in the Republican Party, and compares the storming of the US Capitol by a pro-Trump mob to Kristallnacht in his native Austria. "They trampled the very principles on which our country was founded," Schwarzenegger says of Wednesday's rioters.
