Amid his revelation of unreported income, the Washington Post is calling for New York Congressman Charlie Rangel to step down as chairman of the House Ways and Means Committee.

In an editorial in today's edition, the paper calls Rangel's amended disclosure form a "treasure trove of outrage."

Newly-filed disclosures show that Rangel failed to report at least half a million dollars in assets in 2007.

The paper says, "much more is expected and demanded of those entrusted with chairmanships and the power that comes with them, especially when it involves the nation's purse strings."

Rangel's office released a statement today defending his actions, highlighting the fact that the congressman voluntarily turned over his records for examination and hired a special accountant to examine his financial statements.

"These disclosures, recently made public, have not revealed any evidence of personal gain," said the statement. "It should not be forgotten that it was Congressman Rangel himself who decided to subject himself to this scrutiny. Common sense tells you that someone who has something to hide would not make full disclosure of his finances in the middle of an investigation."
