Section 889 of the 2019 NDAA: The Huawei and ZTE ban
Congress banned federal agencies and their contractors from using equipment from Huawei and ZTE, citing national security risks from backdoors and remote access. The ban later extended to requiring rural carriers to rip out existing Huawei and ZTE gear.
Rural carriers received federal funds to replace the equipment.
It set the precedent for ordering removal of foreign equipment already installed in U.S. critical infrastructure, not just blocking future purchases.
EO 14421 uses the same logic: equipment already in the ground can be ordered removed if it poses a national security risk.
