US President Donald Trump has signed the Defense Authorization Act into law. Section 889 ( PROHIBITION ON CERTAIN TELECOMMUNICATIONS AND VIDEO SURVEILLANCE SERVICES OR EQUIPMENT) bans use by government agencies and contractors of Huawei or ZTE technologies. 

The language of the act is ambiguous and doesn't clearly list what technology is or isn't covered by the prohibition. 

ZTE and Huawei should not be used to access government systems that display personal data, therefore it is safe to assume that most agencies and contractors will purge their networks of systems designed or that use these technologies.

I have not yet seen an official response from either of the tech complanies.

Stay tuned.
