On August 13, 2018, the John S. McCain National Defense Authorization Act (NDAA) for Fiscal Year 2019 was signed into law. Broadly speaking, the NDAA is an annual bill that specifies the budget and expenditures for the Department of Defense and tends to pass without garnering much public attention. However, this particular version contained an interesting wrinkle: Section 889 of the 2019 NDAA prohibited federal agencies, their contractors, and grant or loan recipients from procuring or using “telecommunications and video surveillance services or equipment” from several specific Chinese companies.
