** FILE ** Charles Keating, Jr., right, glances at the cameras as he stops outside Federal court following a hearing in Los Angeles in this Feb. 5, 1998, file photo. McCain's ethics entanglement with a wealthy banker ultimately convicted of swindling investors was such a disturbing, formative experience in his political career that he compares the scandal in some ways to the five years he was tortured as a prisoner of war in Vietnam. In his early days as a freshman senator, McCain was known for accepting contributions from Charles Keating Jr., flying to the banker's home in the Bahamas on company planes and taking up Keating's cause with U.S. financial regulators as they investigated him.
