evidence: In a letter reviewed exclusively by Newsweek, sent last week to Attorney General Merrick Garland and to the head of the FBI Christopher Wray and Secretary of State Anthony Blinken, the 13 lawmakers warned of "systemic influence operations from our principal geopolitical adversary"—China—and said the U.S. government was not responding adequately to the challenge. [...] In April, FBI Director Wray said that risks posed by the Chinese government to U.S. national and economic security were "upon us now." [...] In their letter, the U.S. lawmakers demanded a classified briefing from Garland, Wray and Blinken to answer questions including the "current counterintelligence understanding" of operations run by China's State Security Ministry and the CCP's United Front Work Department in the United States.
