Trump's CISA nominee escorted from Coast Guard amid confirmation dispute

Sean Plankey, President Trump’s nominee to lead the Cybersecurity and Infrastructure Security Agency, had his access badge taken and was escorted out of Coast Guard headquarters on Monday, though sources told reporters he still "remains the nominee" to lead CISA. The episode compounds months of uncertainty over his confirmation and comes as lawmakers and agency staff warn that leadership gaps threaten the security of critical infrastructure, including health systems.

Plankey has been serving in a Coast Guard advisory role "for about the past year," Nextgov and FCW reported, and testified at his Senate Homeland Security and Governmental Affairs Committee confirmation hearing on July 24, 2025. He previously held Energy Department cybersecurity roles in the first Trump administration and served on the National Security Council, according to reporting. Two people familiar with his Coast Guard departure told Nextgov/FCW he is expected to leave the Coast Guard "this week" and could receive an award ceremony "in the coming days."

But the status of his nomination is disputed. CyberScoop reported on Dec. 4, 2025, that Plankey's nomination "appears to be over" after he was excluded from a Senate vote to move forward on a panel of Trump administration picks. By contrast, a Politico Pro excerpt said the White House included Plankey in a list of more than 60 presidential nominees it sent to the Senate for confirmation, characterizing that move as a renomination and an "unambiguous vote of confidence." The sequence and timing of those developments are not fully reconciled in public accounts.

The scramble at CISA is part of broader turbulence across U.S. cyber leadership. Jen Easterly left the agency in January; Bridget Bean has since departed; and Deputy Director Madhu Gottumukkala, who led CISA in an acting capacity at times, was reassigned to a post at DHS headquarters, CybersecurityDive reported. Nick Andersen, executive assistant director for CISA’s Cybersecurity Division, "will step in as acting director," CybersecurityDive said, and was described by staff as bringing more senior cybersecurity experience that gives "some demoralized employees hope." One person familiar with the matter told CybersecurityDive, "I’d hope Nick brings more stability to the agency," and "I don’t think we’ll get that until Plankey comes in, though."

The churn extends to military cyber commands. DefenseScoop reported that President Trump nominated Lt. Gen. Joshua Rudd to lead the National Security Agency and U.S. Cyber Command following the abrupt ouster of the previous NSA/Cybercom leader in April. Sen. Mark Warner warned that delays and vacancies at the top leave the country less secure, saying he looked forward to reviewing Rudd's nomination but that "this kind of chaos and vacancy at the top makes America less safe."

For hospitals, clinics, and local public health agencies that rely on digital systems for patient records, emergency dispatch, and vaccine logistics, leadership uncertainty at CISA raises practical risks. CISA is tasked with protecting critical infrastructure, and lawmakers questioned Plankey in July about election security and the agency’s "slashed workforce," CyberScoop reported. The Senate has moved large blocks of nominees at once in the past — 48 were confirmed in a single September action, CyberScoop noted — but partisan holds and internal scrutiny, including a reported failed polygraph involving Gottumukkala, have complicated confirmations this year.

Officials at DHS, the Coast Guard, and the White House declined public comment where reporters sought clarification in prior coverage, and key dates and reasons for the Coast Guard badge action have not been disclosed in available reports. With implementation of a national cybersecurity strategy on the agenda, the competing accounts of Plankey’s status and the rapid turnover at the agency leave hospitals, emergency services, and other vulnerable communities watching closely.
