CISA Director Nominee Plankey Withdraws After 13-Month Senate Stall

Sean Plankey withdrew his nomination on April 23, citing both 13 months without Senate confirmation and his family's need for 'greater certainty and work life balance,' per his letter to the White House Presidential Personnel Office. Trump had originally nominated Plankey in March 2025 and re-nominated him early in 2026 after his first nomination lapsed; the Senate Homeland Security Committee had advanced his nomination in July 2025 before the re-nomination cycle reset the process. CISA is currently led by Acting Director Nick Andersen, and the Trump administration has not indicated a replacement nominee.

Analysis
Plankey's withdrawal after a 13-month stall spanning two nomination cycles and a lapsed committee advance leaves CISA operating under Acting Director Andersen while the agency coordinates the AA26-113A China advisory response, manages Iran-war-related critical infrastructure defense, and absorbs workforce reductions. The double-nomination failure is structural rather than personal: Plankey's qualifications were not contested, and his withdrawal letter cited family burden rather than policy disagreement, indicating the confirmation pipeline itself is the bottleneck. Without a confirmed director, CISA enters any next escalation phase of the Iran conflict without a principal advocate in National Security Council deliberations.
