Huawei Suing U.S. Government Over Ban

Huawei is suing the U.S. government because its products were banned from being used by federal agencies.
According to one of the people familiar with the matter, Huawei’s lawsuit is likely to argue that the provision is a “bill of attainder,” or a legislative act that singles out a person or group for punishment without trial. The Constitution forbids Congress from passing such bills.
