Chinese telecom giant Huawei sued the U.S. government Wednesday, asserting that Congress violated the Constitution last year when it barred federal agencies from using the company's technology.

Lawmakers shut out Huawei over fears that the Chinese government can tap the company's wireless networking equipment to spy on Americans. But Huawei's attorneys argue that Congress cannot single out a company that has not been found guilty of wrongdoing.

The lawsuit — filed in federal court in the Eastern District of Texas, home to Huawei's U.S. headquarters in Plano — is the latest twist in an escalating legal and public relations battle taking place against the backdrop of the U.S.-China trade talks.
