Keating was more than a constituent to McCain--he was a longtime friend and associate. McCain met Keating in 1981 at a Navy League dinner in Arizona where McCain was the speaker. Keating was a former naval aviator himself, and the two men became friends. Keating raised money for McCain's two congressional campaigns in 1982 and 1984, and for McCain's 1986 Senate bid. By 1987, McCain campaigns had received $112,000 from Keating, his relatives, and his employees--the most received by any of the Keating Five. (Keating raised a total of $300,000 for the five senators.)
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 above may be one reason that Cindy McCain does not want her tax returns made public. Her privilege, but not overly sage in a national Presidential contest.
