Some elements inside the Trump administration are pushing for a nationalization of the next-generation (5G) cell network buildout. The idea would be to build one national network, owned and paid for by the government. Vodkapundit points out that this would represent a single point of failure, and that's an excellent reason to build it via the usual private means.
I'll also add the likely real driving force behind this proposal: Such a network would represent a single point of surveillance. It's much easier for the government to evesdrop on everyone in the country when they own the cell phone network outright. None of those pesky warrants or third-party companies that might fight them in court.
