Ex-Cyber Chief Targeted by Trump Vows to Fight Administration

Chris Krebs, the onetime director of the US Cybersecurity and Infrastructure Security Agency, is vowing to fight the Trump administration full-time after it stripped him and his employer of their security clearances.

Krebs said he has resigned from SentinelOne Inc., where he worked as chief intelligence and public policy officer, in order to challenge the administration and its actions. The executive, who had served under Donald Trump during the president’s previous term, was the subject of an April 9 executive order suspending his security clearance pending an investigation.
