What led Congress to investigate Goldman Sachs?

Congress investigated Goldman Sachs primarily due to its role in the 2008 financial crisis, particularly concerning the sale of mortgage-backed securities. Lawmakers were concerned about allegations that the firm misled investors about the quality of these securities and profited from the ensuing market collapse. This scrutiny was part of a broader examination of Wall Street practices and regulatory failures that contributed to the crisis. The investigation aimed to ensure accountability and prevent similar practices in the future.
