Key Discussion Points & Insights

1. Federal CIO Greg Barbaccia Stepping Down

[00:30]

Greg Barbaccia announced his resignation via email to the CIO Council, stating his last day will be August 31, 2026.
Barbaccia began his tenure as Federal CIO in January 2025 under the Trump administration.
He simultaneously served as the federal Chief AI Officer, playing a pivotal role in shaping AI policy, oversight, and adoption across government.

Succession:

Thomas Flagg, recently brought on as Deputy Federal CIO (formerly Department of Education CIO), is expected to serve as Acting CIO following Barbaccia’s departure.
- “Flagg would be the default acting official with Barbaccia’s departure, according to a government chief information officer who told FedScoop on the condition of anonymity to be more candid.” [01:15]

Notable Quote:

“I’ve made the difficult decision to leave government and my time as federal CIO is coming to an end.” [00:38]

2. DIU’s Major Tech Reorganization

[02:05]

The Defense Innovation Unit (DIU) is undergoing a sweeping reorganization, reducing its operational portfolios from seven to three.
New focus areas:
- Drones & Autonomous Warfare
- Kill Webs
- “10X Technologies” (those enabling non-incremental leaps in price, speed, or capability)

Purpose of Reorganization:

The reorg, initiated by DIU Director Owen West (appointed in the second Trump administration), aims to accelerate delivery of combat power and outcomes to the U.S. military with greater speed and efficiency.
The intent is to “concentrate DIU’s experts and resources on a smaller, more focused set of real world problem areas... deliver outcome-driven, reportable combat power to the US Military at faster and less expensive rates.” [02:40]

Structural Change:

Previous seven portfolios (under the Biden admin): AI, autonomy, cyber, energy, human systems, space, and emerging technology.
Moving forward, AI will be “embedded horizontally in all activities as opposed to a standalone DIU portfolio.” [03:15]

Notable insight:

Two defense officials involved in the reorg spoke to Defense Scoop anonymously to preview these changes ahead of an official Department of Defense announcement.

Notable Quotes & Memorable Moments

Greg Barbaccia’s Farewell:

“I’ve made the difficult decision to leave government and my time as federal CIO is coming to an end.” ([00:38])
On DIU’s Reset:
- “This shakeup and reset is intended to concentrate DIU’s experts and resources on a smaller, more focused set of real world problem areas, so the hub can deliver outcome-driven, reportable combat power to the US Military at faster and less expensive rates.” ([02:40])

Greg Barbaccia is stepping down as federal CIO and leaving government at the end of August, he said in an email to the CIO Council on Tuesday. Barbaccia wrote to CIOs on the council in his email, obtained by FedScoop, quote, I'm writing to share that I've made the difficult decision to leave government and my time as federal CIO is coming to an end. Barbaccia, who joined the Trump administration as its top IT official in January 2025, said his last day in the role will be August 31. Barbaccia's departure comes just months after he brought on former Department of Education CIO Thomas Flagg to be his deputy.

Now moving on to other news, the Defense Innovation Unit is undergoing a major reorg that will overhaul and collapse its operational portfolios from seven to three technology priorities where speed, scale and lethality intersect, two sources told Defense Scoop this week. One senior defense official and one defense official familiar with this realignment said the Pentagon would likely reveal diu's near term plans and new internal structure publicly this week. The officials requested anonymity to speak freely ahead of the Defense Department's official forthcoming announcement, but they suggested that this shakeup and reset is intended to concentrate diu's experts and resources on a smaller, more focused set of real world problem areas, such as so the hub can deliver outcome driven, reportable combat power to the US Military at faster and less expensive rates. Diu's recently installed director under the second Trump administration, Owen west, initiated the reorg. The three new portfolios and priority topics that the unit will be structured around, according to the two officials, are drones and autonomous warfare kill webs and so called 10X technologies or those that deliver non incremental shifts in price, speed or capability. The seven portfolios, the unit previously prioritized under the former Biden administration, covered AI, autonomy, cyber energy, human systems, space and emerging technology. Moving forward, the sources told Defense, Scoop AI will be embedded horizontally in all activities as opposed to a standalone DIU portfolio.
