"As I said when we opened our investigation, Enron employees have gotten the short end of the stick in the collapse of this company and we are committed to doing everything we can to help them."
The Dow Jones News Service said the department claimed the suit aims to recover losses that Enron employees suffered due to alleged mismanagement of two of the company's pension plans.
The lawsuit alleges Enron and the executives violated the Employee Retirement Income Security Act when they failed to "consider the prudence of Enron stock as an appropriate investment for the retirement plan," the Labor Department said in a statement.
