5G mobile data networks subject to nationalization by the US government

Axios News reports that the Trump administration is considering the prospect of nationalizing the forthcoming 5G network when it begins to be built in the United States.  Naturally, this idea is controversial, as private enterprise has been in charge of much of commercially used spread spectrum technology in the the USA for decades.
The proposal would limit itself to 5G networks only, and not to previous technologies or different ones.
