U.S. Attorney General William Barr identified China as the biggest threat to the United States and said they’re “engaged in a full-court blitzkrieg” to steal our technology, during an interview Wednesday with Fox News host Laura Ingraham.

“China is a very serious threat to the United States, geopolitically, economically, militarily, and a threat to the integrity of our institutions given their ability to influence things,” Barr said.

Further, Barr said the Department of Justice is trying to “tighten up” on American universities and businesses working with China.

He added, “A number of universities are working closely with the government to understand what the nature of the threat is, but it’s not just universities. Universities are part of the problem, but a lot of American business is just for short-term profit or what they see as a short term profit. They know over the long run it’s not going to be long term benefit to their business.”
