Trump's Pick to Run CISA Just Asked to Drop Out — Leaving the US Without a Cyber Chief
Sean Plankey, Donald Trump's nominee to lead the Cybersecurity and Infrastructure Security Agency, asked to withdraw his nomination on April 23, 2026 — citing Senate gridlock. His nomination had been pending since March 2025. The United States now has no confirmed head of its primary federal cybersecurity agency, and no obvious replacement in the pipeline.
Why the Nomination Failed
Plankey's withdrawal had nothing to do with his qualifications. Senator Rick Scott blocked the nomination over an unrelated Coast Guard contract from Plankey's previous government role. The hold was a political maneuver, not a substantive objection. The result: over a year of Senate inaction on a critical national security position.
Nick Andersen is currently serving as acting CISA director. The previous acting director, Madhu Gottumukkala, departed in February 2026 after less than a year in the role. CISA has been in leadership limbo for the better part of a year and a half.
What CISA Has Been Dealing With in the Meantime
The leadership gap has coincided with serious headwinds for the agency. The Trump administration proposed slashing CISA's budget by over $700 million. The agency has endured multiple partial government shutdowns and staff furloughs. Key personnel have departed. For an agency whose entire function is to protect critical US infrastructure from cyberattacks, persistent leadership instability is not an abstract problem.
Why This Matters Beyond Washington
CISA is responsible for defending federal systems, warning the private sector about active threats, and coordinating responses to large-scale cyber incidents. Water treatment plants, power grids, hospitals, election infrastructure — CISA's mandate covers all of it. A leadership vacuum at the top translates to slower decision-making exactly when speed matters most.
My Take
Senator Rick Scott killed a cybersecurity nomination over a Coast Guard contract dispute. That is what actually happened here. The US faces daily nation-state cyber operations from China, Russia, and Iran — and a sitting senator decided personal political leverage was more important than having a confirmed cyber chief. There's no diplomatic way to characterize that.
