OPM tech lead Greg Hogan leaves post

The Office of Personnel Management’s top technology official, Greg Hogan, has left the job he’s held at the agency since day two of the Trump administration. 

His last day on the job was Tuesday, an OPM spokesperson confirmed with Nextgov/FCW. Peryn Ashmoore, currently OPM’s assistant director of enterprise learning and a longtime federal employee, has taken over as the acting chief information officer for the agency. 

Hogan became the CIO on the second day of Trump 2.0 after the agency’s former CIO, Melvin Brown II, was ousted after only a week in the job. Hogan previously worked at comma.ai, which produces driver assistance technology meant to make cars semi-autonomous. OPM did not provide details on who Hogan’s permanent replacement will be or what his next steps are.

OPM, which is essentially the government’s HR agency, was an early focal point for the controversial Department of Government Efficiency. Like other federal agencies, its workforce has shrunk over the last eight months as the administration has enacted layoffs and offered incentives for employees to leave voluntarily.

Longtime venture capital executive Scott Kupor started as the OPM director in June.

As the head of OPM’s technology, Hogan hasn’t had a large outward presence, but presumably has been involved with high-profile tech priorities under this administration. 

OPM has touted progress made on modernizing the government’s retirement processes, an effort that started before Trump took office in January.

The agency has also been sued several times for its handling of data — specifically DOGE associates’ access to sensitive data at OPM. 

At the center of one of those lawsuits is a government-wide mass email system set up in the early days of the administration and used to send out an initial delayed resignation offer to federal employees and collect requested bullet points from federal employees detailing their work, a policy that’s since been axed.

Hogan signed off on a privacy impact assessment issued for the government-wide email system after the agency was sued by anonymous federal employees alleging that OPM violated the law by not publishing a PIA before deploying the new system. 

His signature set the document apart from other PIAs at OPM, which are typically signed by privacy officials at the agency. 

In May, Hogan testified for hours in another case challenging DOGE access to data under the Administrative Procedures Act and the Privacy Act, saying that several DOGE engineers were given high-level administrative access to work on priorities like implementing a hiring freeze. That level of access was later revoked for several engineers, he said.

In another case, an appeals court ruled last month that DOGE can access federal employees’ personal information and files, overturning an earlier injunction blocking DOGE access.
