Isn't it odd that NO ONE ever mentions this, given what is going on in the banking industry and McCain's presidential candidacy?

We're all sort of at the age where we might not have been paying attention, but the S&L crisis was a pretty big deal in the 1980s. The Keating Five were 5 US Senators who received campaign contributions from Charles Keating in exchange for obstructing the investigation into the collapse of a particular S&L that Keating was head of.

John McCain was one of those Senators.

For whatever reason, this fact has been stricken from history and is NEVER mentioned in the mainstream media.

From wikipedia:

The Keating Five (or Keating Five Scandal) refers to a Congressional scandal related to the collapse of most of the Savings and Loan institutions in the United States in the late 1980s.

Following the deregulation of the banking industry in the 1980s, savings and loan associations (also known as thrifts) were given the flexibility to invest their depositors' funds in commercial real estate. (Previously, they had been restricted to investing in
residential real estate.) Many savings and loan associations began making risky investments. As a result, the Federal Home Loan Bank Board, the federal agency that regulates the industry, tried to clamp
down on the trend. In so doing, however, the FHLBB clashed with the Reagan administration, whose policy was deregulation of many industries, including the thrift industry. The administration declined to submit budgets to Congress that would request more funding for the FHLBB's regulatory efforts.

In 1989, the Lincoln Savings and Loan Association of Irvine, Calif., collapsed. Lincoln's chairman, Charles H. Keating Jr., was faulted for the thrift's failure. Keating, however, told the House Banking Committee that the FHLBB and its former chief Edwin J. Gray were
pursuing a vendetta against him. Gray testified that several U.S. senators had approached him and requested that he ease off on the Lincoln investigation. It came out that these senators had been beneficiaries of $1.3 million (collective total) in campaign contributions from Keating.

This allegation set off a series of investigations by the California government, the United States Department of Justice, and the Senate Ethics Committee. The ethics committee's investigation focused on five senators: Alan Cranston (D-CA); Dennis DeConcini (D-AZ); John Glenn (D-OH); John McCain (R-AZ); and Donald W. Riegle, Jr. (D-MI), who became known as the Keating Five.

After months of testimony revealed that all five senators acted improperly to differing degrees, the senators continually said they were following the status quo of campaign funding practices. In August 1991, the committee concluded that Cranston, DeConcini, and Riegle's conduct constituted substantial interference with the FHLBB's enforcement efforts and that they had done so at the behest of Charles Keating. The committee recommended censure for Cranston and criticized the other four for "questionable conduct."

As it happened, Cranston, who was nearly 80 years of age, had already decided not to run for re-election in 1992. DeConcini and Riegle continued to serve in the Senate until their terms expired, but they did not seek re-election in 1994.

Glenn did choose to run for re-election in 1992 and it was anticipated that he would have some difficulty winning a fourth term in the Senate. However, Glenn handily defeated Lieutenant Governor R. Michael DeWine for one more term in the Senate before retiring in 1999.

The scandal was followed by a number of attempts to adopt campaign finance reform—spearheaded by U.S. Sen. David Boren (D-OK)—but most attempts died in committee. A weakened reform was passed in 1993. Substantial campaign finance reform was not passed until the adoption of the McCain-Feingold Act in 2002.
