Dozens of Chinese influence operations funded by its Communist Party in American universities have been declared a national security threat by the Department of War.

The organizations are called Confucius Institutes, according to the announcement by Secretary Pete Hegseth.

“Let this be a lesson to any country trying to steal our hard-earned inventions or turn our young people against their own country. We’re done with that; no more; and never again,” Hegseth said.
