Final answer:
The GSA furniture investigation likely began with a GAO report or congressional inquiry into federal spending and oversight.
Step-by-step explanation:
The investigation into the GSA's furniture acquisition likely started due to a GAO report or congressional inquiry. The Government Accountability Office, known as the Congressional watchdog, investigates federal spending and is responsible for providing Congress with audits and reports.
Concerns over government bureaucracy and public skepticism can lead to rigorous oversight, prompt investigations, and increased transparency. In this case, the heightened oversight might have revealed the payoffs to GSA inspectors by the New Jersey furniture manufacturer.
