U.S. lawmakers have warned AT&T about doing business with Chinese phone-maker Huawei, citing security concerns, reports Reuters.
Why it matters: Federal regulators have blocked several Chinese acquisitions and partnerships with American companies, following President Donald Trump's pledge to crack down on the United States' largest trading partner. National security officials fear that data from Huawei devices could be used for foreign espionage by Chinese intelligence services.
