An investigation into possible accounting irregularities at Enron Corp. conducted by Houston’s Vinson & Elkins in the fall of 2001 was “bogus” in the estimation of the Enron employee whose complaints to former Enron Chairman Kenneth Lay prompted the probe.

Sherron Watkins, the one-time Enron vice president who brought her complaints to Lay in August 2001, testified Wednesday in the Houston criminal trial of Lay and former Enron Chief Executive Officer Jeffrey Skilling that the V&E lawyers who did the investigation at the company’s behest did not contact all of the former and current Enron employees she thought might provide information about the accounting she found problematic.
