In 2003, White refused to publicly rebuke General Eric Shinseki for his statement to the Senate Armed services committee that it would take "something in the order of several hundred thousand soldiers" to occupy Iraq after invasion. This, combined with White's actions on the Crusader, disagreements with Rumsfeld on the Stryker project, and his distracting association with Enron including the selling of restricted Enron stock through "private investments" (derivatives), prompted Rumsfeld to demand White's resignation. White resigned on April 25, 2003.
