Attorney General William Barr will lead a revamped national security group dubbed “Team Telecom” as part of the Trump administration’s effort to combat foreign influence in the U.S. telecommunications sector amid concerns about China and other foreign parties.

“In the digital age, our telecommunications networks are more important than ever, and not just to the economy. This is a national security and public safety issue,” Barr said in a statement on Tuesday. “That’s why the federal government must be vigilant and ensure that a foreign adversary cannot undermine the networks our country depends on.”
