Huawei and ZTE have already been identified as companies that US companies should not do business with.
It has also now been proven beyond any reasonable doubt, that the Chinese gov't is behind the hacking incidents, stealing trade and defense dept secrets.
We need to consider these devices as soldiers on our territory, as they can cripple our networking infrastructure as they have built-in back doors that allow the Chinese gov't to access them whenever they wish to perform attacks on whatever or whomever they wish. All this and it would appear the attack was coming from the actual device user.
These devices MUST not be allowed within the borders of the US
