Pepe Farms almost remembered reading about Wolf, so I asked Grok.
The person you're likely referring to is James Wolfe (often spelled "James A. Wolfe" or "James A. Wolf" in some references), the former director of security for the Senate Select Committee on Intelligence.
He was arrested on June 7, 2018, during President Trump's first term. The charges were three counts of making false statements to the FBI (lying about his contacts with reporters as part of a leaks investigation involving classified information). President Trump publicly praised the arrest, calling Wolfe "a very important leaker" in comments to reporters.
This case was notable because it involved the first known instance during the Trump administration of the Justice Department seizing records from a reporter (specifically, phone and email records from a New York Times reporter as part of the probe). Wolfe, who had served in that Senate role for nearly 30 years before retiring shortly before the arrest, pleaded not guilty initially but later reached a plea deal in late 2018, pleading guilty to one count of lying to the FBI. He was sentenced to probation rather than prison time.
No high-profile figure named "Wolf" (or Wolfe) who was actually part of the Trump administration (like Chad Wolf, the former acting DHS secretary) was arrested during that time—Chad Wolf served in the administration without any arrest.
Minute mark 9:50 in the Prometheus report, Trump mentioned Wolf.
