Here are some quotes I found particularly interesting;
"Mr. McCain helped found a nonprofit group to promote his personal battle for tighter campaign finance rules. But he later resigned as its chairman after news reports disclosed that the group was tapping the same kinds of unlimited corporate contributions he opposed, including those from companies seeking his favor. He has criticized the cozy ties between lawmakers and lobbyists, but is relying on corporate lobbyists to donate their time running his presidential race and recently hired a lobbyist to run his Senate office."
During Mr. McCain’s four years in the House, Mr. Keating, his family and his business associates contributed heavily to his political campaigns. The banker gave Mr. McCain free rides on his private jet, a violation of Congressional ethics rules (he later said it was an oversight and paid for the trips). They vacationed together in the Bahamas. And in 1986, the year Mr. McCain was elected to the Senate, his wife joined Mr. Keating in investing in an Arizona shopping mall.
Mr. Keating had taken over the Lincoln Savings and Loan Association and used its federally insured deposits to gamble on risky real estate and other investments. He pressed Mr. McCain and other lawmakers to help hold back federal banking regulators.
For years, Mr. McCain complied. At Mr. Keating’s request, he wrote several letters to regulators, introduced legislation and helped secure the nomination of a Keating associate to a banking regulatory board.
By early 1987, though, the thrift was careering toward disaster. Mr. McCain agreed to join several senators, eventually known as the Keating Five, for two private meetings with regulators to urge them to ease up. “Why didn’t I fully grasp the unusual appearance of such a meeting?” Mr. McCain later lamented in his memoir.
When Lincoln went bankrupt in 1989 — one of the biggest collapses of the savings and loan crisis, costing taxpayers $3.4 billion — the Keating Five became infamous. The scandal sent Mr. Keating to prison and ended the careers of three senators, who were rebuked by the Senate Ethics Committee in 1991 for intervening. Mr. McCain, who had been a less aggressive advocate for Mr. Keating than the others, was reprimanded only for “poor judgment” and was re-elected the next year.
Some people involved think
Mr. McCain got off too lightly. William Black, one of the banking
regulators the senator met with, argued that Mrs. McCain’s investment
with Mr. Keating created an obvious conflict of interest for her
husband. (Mr. McCain had said a prenuptial agreement divided the
couple’s assets.) He should not be able to “put this behind him,” Mr.
Black said. “It sullied his integrity.”"
Theres more to it than this though, so I highly suggest reading the article, and please don't attack me for the quotes I pulled, I felt it represented the meat of the article, and it's hard to cut a four page article down to NS size.
