Lawmakers Urge AT&T to Cut Ties with Huawei, Citing National Security

U.S. lawmakers are urging AT&T Inc., the No. 2 wireless carrier, to cut commercial ties to Chinese phone maker Huawei Technologies Co. Ltd. and oppose plans by telecom operator China Mobile Ltd. to enter the U.S. market because of national security concerns, two congressional aides said. The warning comes after the administration of U.S. President Donald Trump took a harder line on policies initiated by his predecessor Barack Obama on issues ranging from Beijing’s role in restraining North Korea to Chinese efforts to acquire U.S. strategic industries.
