A bipartisan group of senators led by Senate Minority Leader Charles Schumer (D-N.Y.) on Tuesday “strongly urged” the British Parliament to reject Chinese telecom group Huawei and exclude it entirely from their 5G networks.

The British House of Commons is set Wednesday morning to debate the decision by the United Kingdom’s National Security Council in January to allow Huawei equipment in “periphery networks” while banning the company’s equipment from more secure networks.

In a letter sent to members of Parliament on Tuesday night, Schumer, Sen. Ben Sasse (R-Neb.) and a bipartisan group of almost two dozen other senators underlined national security risks created through use of the company’s equipment, asking them to “revisit” their country’s decision on Huawei.

“Given the significant security, privacy, and economic threats posed by Huawei, we strongly urge the United Kingdom to revisit its recent decision, take steps to mitigate the risks of Huawei, and work in close partnership with the U.S. on such efforts going forward,” the senators wrote.
