Former CISA chief Chris Krebs has pledged to fight against a federal investigation initiated by President Trump. In a recent interview, Krebs announced his resignation from cybersecurity firm SentinelOne to challenge allegations that he falsely denied the 2020 election was rigged. Trump, who appointed Krebs in 2018, stripped him of his security clearance after Krebs publicly debunked election fraud claims. Krebs criticized the government's actions as punitive against dissenters, joining others in opposing Trump's use of executive power to target critics.
