The United States hit back against Huawei on Wednesday, asking a federal court in Texas to dismiss the Chinese firm's lawsuit against a US government ban on its products. Huawei had filed the lawsuit in March, arguing that a law preventing US federal agencies from buying its products violates the US constitution by singling out an individual or group for punishment without trial. Lawyers for the US Department of Justice challenged that claim in a filing on Wednesday, saying the law wasn't unconstitutional punishment, but rather the "logical next step" to protect the country and ensure China isn't given "a strategic foothold" in US networks. The lawyers said American lawmakers and officials had been warning against Huawei's potential use for Chinese "cyber-activity" for over a decade, adding that the company was using outdated arguments from the Civil War and Cold War eras. The portion of the law in question "does not sentence Huawei to death, imprison it, or confiscate its property," they argued, moreover it "plainly does not preclude Huawei from engaging in its chosen profession."
