Madhu Gottumukkala faces polygraph fallout as 6 CISA staff placed on leave, but here’s the shocking twist nobody expected

Madhu Gottumukkala, acting director of the Cybersecurity and Infrastructure Security Agency, faces significant fallout after reportedly failing a polygraph test. At least six CISA career staff members have been placed on administrative leave. The controversy has raised serious questions about leadership accountability and agency stability.

What Led to the Polygraph Test Dispute?

In July 2025, Gottumukkala sought access to a highly sensitive intelligence program shared with CISA by another federal agency. Multiple senior staff members warned him the access was unnecessary. They explained that less classified versions of the materials would serve his leadership role without requiring the security clearance.

Despite these warnings, Gottumukkala insisted on pursuing access. His initial request was denied by a senior official in June who determined no urgent need-to-know existed. However, when that official was placed on leave for unrelated reasons in late June, a second request submitted by Gottumukkala himself was approved in early July, setting the polygraph requirement in motion.

The Failed Test and Immediate Fallout

Gottumukkala took the polygraph examination in the final week of July 2025 and failed the test, according to current and former cybersecurity officials. The test was designed to determine his eligibility to review classified materials designated as a controlled access program by the originating intelligence agency.

Within days of the failed test, six career staff members faced investigation. On August 1, staffers including Jeffery Conklin (CISA’s chief security officer), Masoom Chaudhary (deputy chief of staff), and four others received letters stating they had provided “false information” to Gottumukkala about the polygraph requirement.

DHS Claims the Test Was “Unsanctioned”

The Department of Homeland Security characterized the polygraph as “unsanctioned,” claiming career staff misled Gottumukkala into taking a test he didn’t actually need. DHS Spokesperson Tricia McLaughlin stated that Gottumukkala “did not fail a sanctioned polygraph test.”

However, cybersecurity insiders challenged this narrative. Multiple current officials interviewed expressed skepticism about the “unsanctioned” claim, noting that someone in Gottumukkala’s position would ultimately need to sign off on their own polygraph request. DHS also suggested a waiver from senior Trump administration officials could have bypassed the test requirement entirely—a plausible but highly unusual loophole.

“He ultimately chose to sit for this polygraph. There is only one person to blame for that.”

Impact on CISA’s Morale and Stability

The controversy strikes at a tumultuous period for CISA, which has experienced severe instability under the Trump administration. Nearly one-third of agency staff have departed since January 2025. Some employees faced ultimatums to either shift to immigration-related roles within the Department of Homeland Security or leave the agency entirely.

The agency has operated without a permanent Senate-confirmed director since Jen Easterly resigned on January 2025. Gottumukkala, a former South Dakota IT official appointed by Homeland Security Secretary Kristi Noem in May, serves as the de facto leader while Senate confirmation of Trump’s pick, Sean Plankey, remains stalled.

What Happens Next for Gottumukkala and CISA?

The investigation into the six suspended staff members continues under oversight of DHS’s acting general counsel. Polygraph experts note that test results are inadmissible as evidence in most U.S. courts due to reliability concerns, and failures can result from various factors including anxiety or technical errors.

The bigger question facing CISA remains unresolved: will Gottumukkala maintain his acting director position? Career staff have expressed serious concerns about his judgment and accountability, particularly given his agency’s responsibility for protecting federal networks and critical infrastructure. Some describe the organization as chaotic and destabilized by recent leadership decisions.
