More Keating Five memories via Slate:

After McCain's election to the House in 1982, he and his family made at least nine trips at Keating's expense, three of which were to Keating's Bahamas retreat. McCain did not disclose the trips (as he was required to under House rules) until the scandal broke in 1989. At that point, he paid Keating $13,433 for the flights.
And in April 1986, one year before the meeting with the regulators, McCain's wife, Cindy, and her father invested $359,100 in a Keating strip mall.
The Senate Ethics Committee probe of the Keating Five began in November 1990, and committee Special Counsel Robert Bennett recommended that McCain and Glenn be dropped from the investigation. They were not. McCain believes Democrats on the committee blocked Bennett's recommendation because he was the lone Keating Five Republican.
