Sacked auditor denies wrongdoing
The auditor sacked following the collapse of Enron denies any wrongdoing.
David Duncan, who oversaw energy Enron's audits for accountants Arthur Andersen, is due to be interviewed by the House Energy and Commerce Committee.
Arthur Andersen claims that Duncan organised the destruction of documents last October.
It is alleged that the destruction stopped two weeks later when Duncan's assistant e-mailed secretaries to "stop the shredding".
Mr Duncan's lawyer says: "Mr Duncan is cooperating with all investigations. He did nothing wrong."
Mr Duncan claims he followed the instructions of an Andersen in-house lawyer in handling documents.
In December, Houston based Enron, filed for bankruptcy protection with debts of €12.6bn.
Along with Duncan's dismissal, Andersen said four partners in its Houston office would be stripped of management responsibilities.
Among them, Stephen Goddard, an Andersen managing partner, was a major fundraiser for President George W Bush's 2000 election campaign.
Enron was Bush's largest corporate contributor during the campaign.
The Justice Department is pursuing a criminal investigation of the company, once the world's energy trading group with extensive interests in Britain.
