‼️ Huawei is on trial for spending two decades taking trade secrets out of American companies.

On Wednesday, prosecutors showed the jury 54 seconds of what they say that looked like.

Surveillance video from inside T-Mobile's locked robotics lab shows a man reach behind Tappy, the robot T-Mobile built to tap and swipe phone screens, pull out a component and zip it into a black backpack.

Prosecutors say he is a Huawei employee.

They also put an internal Huawei email in front of jurors acknowledging that T-Mobile "would not want to share the details about the robot technology," and say the requests kept coming anyway.

Huawei has pleaded not guilty and says a handful of engineers broke lab rules on their own.
