Former Enron Corp. Chief Executive Jeffrey Skilling told other top executives “they’re on to us,” when a small analyst firm produced a research note critical of the company’s sales to partnerships run by then-Chief Financial Officer Andrew Fastow, a former top executive testified in a bombshell revelation Thursday.

Minutes before that, Skilling said at the May 2001 meeting — attended by company founder Kenneth Lay — that he had “brought Andy here” to talk about those partnerships, called LJM1 and LJM2.
