ProPublica is releasing a trove of disclosure records that detail the finances of more than 1,500 Trump appointees, including former lobbyists, industry executives and at least a dozen officials who declined to identify former clients.

Thousands of companies are jockeying for billions of dollars in Defense Department contracts to build a shield designed to intercept and destroy missiles launched against the United States.

But amid the intense competition, a handful of firms have an important inside connection.

At least four of the companies awarded contracts so far are owned by Cerberus Capital Management, a private equity firm founded by billionaire Steve Feinberg, who until last year ran the company and is now the deputy secretary of defense — the second-highest-ranking official in the Pentagon.

Feinberg oversees the office in charge of the Golden Dome for America project, which is modeled on Israel’s Iron Dome missile defense system.
