Maryland Governor Larry Hogan has announced a TikTok ban on all state-owned government devices after South Dakota Governor Kristi Noem and South Carolina Governor Henry McMaster passed similar bans earlier this month.

Hogan, a two-term Republican who will leave office next month, issued the emergency cybersecurity directive after governors in other states made similar moves and FBI director Chris Wray reiterated concerns about the app being a national security threat.

“There may be no greater threat to our personal safety and our national security than the cyber vulnerabilities that support our daily lives,” Hogan said in a statement. “To further protect our systems, we are issuing this emergency directive against foreign actors and organizations that seek to weaken and divide us.”

“This action represents a critical step in protecting Maryland State systems from the cybersecurity threats caused by foreign organizations,” Maryland’s Chief Information Security Officer Chip Stewart added.

Maryland’s ban adds to a growing number of states that are moving to ban the social media platform.
