The committee chair asked each of the three leaders whether their companies’ equipment contained compo- nents from either Russia or China, basing her question on a recent Interos report that stated that 20 percent of the components in one major elec- tion equipment vendor’s machine came from China.2 All three executives noted that they use Chinese-manufactured components in their election equipment, in part because they did not have viable domestic sources for these components.3 The hearing reflects a broader concern about the exposure that technology supply chains have to China, combined with a widening focus on election security in the United States that gained C O R P O R A T I O N prominence following Russian interference in the election officials around the country to offer cyber- 2016 elections but has extended to encompass many security services and advice.
