No, and 31 Congressmen tried to sue him over that action. However the Supreme Court refused to hear the appeal from the Court of Appeals, which had ruled that the Congressmen had no standing to sue in that case. They also said Congress could cut off funding for that action if they wished, an observed that a vote to do that had failed in Congress (as had one to authorize the bombing, which did pass the Senate).
But that was BJ, this is President Bush. Bush actually read the Constitution, in spite of not being a lawyer.
