US Army Examines TikTok Security Concerns Reuters WASHINGTON/SAN FRANCISCO - The U.S. Army is undertaking a security assessment of China-owned social media platform TikTok after a Democratic lawmaker raised national security concerns over the app's handling of user data, Army Secretary Ryan McCarthy said Thursday. Speaking to reporters at an event at the American Enterprise Institute think tank, McCarthy said he ordered the assessment after the top Democrat in the U.S. Senate, Chuck Schumer, asked him to investigate the possible risks in the military's use of the popular video app for recruiting American teenagers. "National security experts have raised concerns about TikTok's collection and handling of user data, including user content and communications, IP addresses, location-related data, metadata, and other sensitive personal information," Schumer wrote in a Nov. 7 letter to McCarthy. Schumer said he was especially concerned about Chinese laws requiring domestic companies "to support and cooperate with intelligence work controlled by the Chinese Communist Party." .
