The FBI, CIA, and NSA leaders are compact in voicing their distrust of China's two products. It was delivered before the Senate Intelligence Committee.
The FBI and CIA directors also expressed their opinion on recommending the US people not to use suspected products.
"We have a deep concern about the risk of allowing any company or agency belonging to a foreign government that does not share our values to take a position of power on our telecommunications network," said FBI Director Christopher Wray.
It was suspected of potential suspicion of modifying or stealing information for evil interests, as well as in carrying out espionage.
Recently, Senator Tom Cotton of Arkansas and Senator Marco Rubio of Florida submitted a bill that blocked the US government from buying or renting network equipment from ZTE or Huawei.
This is not the first time Huawei has stumbled on problems in the US. In 2012, Huawei and ZTE have been suspected by the US intelligence committee due to potential espionage action.
