Former Enron Corp. Chief Executive Officer Jeffrey Skilling, testifying for the second day at his criminal trial, said on Tuesday that he and co-defendant Kenneth Lay, Enron’s one-time chairman, never conspired together or with others to defraud investors by presenting false and misleading financial statements.

Skilling’s testimony contradicts allegations in United States v. Jeffrey K. Skilling, et al., the federal indictment that includes 28 fraud, conspiracy, making false statements and insider-trading charges against him. Lay faces six fraud and conspiracy charges in the trial, which is in its 11th week in U.S. District Judge Sim Lake’s Houston courtroom.
