CISA Overhauls Leadership After Turbulent Year of Controversy
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has replaced acting director Madhu Gottumukkala with Nick Andersen following a turbulent year marked by staff cuts, security incidents and leadership controversy. CISA said Gottumukkala has been reassigned to the Department of Homeland Security as director of strategic implementation. Reports allege Gottumukkala struggled in the role, including uploading sensitive government documents to ChatGPT, failing a counterintelligence polygraph required for classified access, and presiding over a one-third reduction in staffing. The agency also lost its CIO, Bob Costello, amid internal disputes. The administration has nominated Sean Plankey for the permanent CISA director role; his confirmation remains pending in the Senate after prior objections from Sen. Ron Wyden related to an unclassified telecommunications security report.
Leadership turnover and reported security lapses at CISA — the federal agency responsible for national cybersecurity — affect the U.S. cybersecurity posture and have implications for federal infrastructure, incident response, and trust in handling sensitive data; the pending nomination for a permanent director adds political uncertainty.

CISA Faces Crisis After Major Staffing Cuts and Layoffs
TechCrunch reports that the U.S. Cybersecurity and Infrastructure Security Agency (CISA) is reportedly weakened after staffing cuts, reassignments, and layoffs during the first year of the Trump administration. Sources cited by Cyberscoop and TechCrunch say CISA lost roughly one-third of its staff, has seen key programs (including a counter-ransomware initiative and secure software development efforts) reduced, and had members of its election security team depart. Hundreds of staffers were reportedly reassigned to other Department of Homeland Security units as part of immigration enforcement priorities. CISA has operated without a permanent director since President Donald Trump took office in 2025; Madhu Gottumukkala is serving as acting director and defended the agency’s commitment amid a partial federal shutdown that left CISA operating at about 38% staffing levels.
Head of U.S. AI Safety Agency Resigns After 3 Months
Chris Fall resigned as director of the Center for AI Standards and Innovation (CAISI) after roughly three months, the Commerce Department confirmed, without disclosing a reason. Arvind Raman, director of the National Institute of Standards and Technology (NIST), will serve as CAISI’s acting director. CAISI, housed at NIST within the Commerce Department, is charged with developing technical standards, testing methods and collaborative testing for commercial AI models, including cybersecurity risk assessment. Fall’s departure follows earlier rapid leadership turnover and adds uncertainty about who is leading the administration’s AI policy and oversight as the White House implements a new executive order and the “Gold Eagle” clearinghouse for frontier-model access. The resignation comes amid recent industry and government actions such as a temporary export-control-driven removal of Anthropic models that was later lifted and debate over Chinese open-weight models.
Iran Cyber Threats Rise Amid U.S. Agency Struggles
U.S. cyber officials and private-sector experts warn of an elevated risk of Iran-linked cyberattacks on American businesses and infrastructure as kinetic strikes in the Middle East intensify. The Cybersecurity and Infrastructure Security Agency (CISA) is facing operational strain from a partial government shutdown, staff furloughs, management reshuffles and key departures, which officials and lawmakers say could hamper its readiness. Private cybersecurity firms (CrowdStrike, Google’s Threat Intelligence Group) report increased activity and claims from Iran-linked groups, and major companies and financial institutions are preparing for potential disruptions. Lawmakers and DHS say they are coordinating with intelligence and law enforcement partners, while concerns persist about gaps in CISA’s capacity during the funding lapse.
