Chinese government hackers are busily targeting water treatment plants, the electrical grid, transportation systems and other critical infrastructure inside the US, FBI Director Chris Wray is set to tell House lawmakers on Wednesday in a fresh warning from Washington about Beijing’s global ambitions.

Wray says that that there’s been “far too little public focus” on a cyber threat that affects “every American,” according to a copy of prepared remarks that he is to give before the House Select Committee on the Chinese Communist Party.
