In July 2002, Bush Illegally Shifted $700 Million to Begin War on Iraq

Woodward said he found that the administration quietly shifted money around to pay for early preparations for war in Iraq, without the approval of Congress. He said those preparations included building landing strips and addressing other military needs in Kuwait.
The money, about $700 million, was taken in July 2002 from a budget item that had been approved for the war in Afghanistan, Woodward wrote.
"Some people are going to look at that document called the Constitution, which says that no money will be drawn from the Treasury unless appropriated by Congress," Woodward says in his CBS interview.
