A C.I.A. officer, David Rush, has been arrested after authorities discovered over $40 million in gold bars at his home. David Rush, age 49, served in the agency’s Directorate of Science and Technology for 17 years. His previous work included a connection with Stephen A. Feinberg, now the deputy secretary of defense.

Officials indicate that Rush and Feinberg’s interactions were likely minimal. They reportedly first connected during President Trump’s first term, while Feinberg chaired the President’s Intelligence Advisory Board. The board advises the White House and spy agencies on intelligence matters.

Feinberg founded Cerberus Capital Management and showed interest in C.I.A. technology. He kept a close eye on the Directorate of Science and Technology both during his advisory board tenure and after joining the Pentagon.

The purpose of Rush’s gold bars issued by the C.I.A. remains unknown. Former officials speculate that a covert program might explain his access to substantial funds. However, sources briefed on the investigation state that Feinberg and the Pentagon are not linked to Rush’s activities involving the gold bars.

While the Pentagon has not responded to requests for comment, the C.I.A. declined to comment. NBC News initially reported Rush’s connection to Feinberg.

Currently held in jail, Rush faces charges of stealing public money through fraudulent time sheets. Court documents reveal accusations of inflating academic credentials and falsifying work history.

From November to March, court records show Rush requested and received millions in gold bars and foreign currency for purported work expenses. However, a C.I.A. review could not determine the location of the gold and currency.

The C.I.A.’s alert prompted an F.B.I. search of Rush’s home, uncovering 303 gold bars, each weighing around 2.2 pounds.
