The New York Times wonders why the president believes that a wartime contracting commission and protection for contractor fraud whistleblowers would hinder his constitutional duty to faithfully execute laws. The [national defense authorization] bill included four important provisions that Mr. Bush decided he will enforce only if he wants to. The president said they impinged on his constitutional powers. We asked the White House to explain that claim, but got no answer, so we'll do our best to figure it out. The first provision created a commission to determine how reliant the government is on contractors in Iraq and Afghanistan, how much waste, fraud and abuse has occurred and what has been done to hold accountable those who are responsible. Congress authorized the commission to compel government officials to testify. Perhaps this violated Mr. Bush's sense of his power to dole out contracts as he sees fit and to hold contractors harmless. The same theory applies to the second provision that Mr. Bush said he would not obey: a new law providing protection against reprisal to those who expose waste, fraud or abuse in wartime contracts.
