In 1992, many House members were suspected of bouncing checks from accounts they held at the so-called "House Bank" -- a loose operation that allowed member of Congress to cash their checks but kept shoddy records and often were quite delayed in recording deposits or withdrawals.
Although the lawmakers had broken no laws and many did not even know they were bouncing checks, several took advantage of the bank system and many voters viewed the scandal as a blatant abuse of power.
