This just in from FoxNews; the parents of a serviceman already deployed in the Persian Gulf are suing the President, stating in the complaint that he has no power to wage war without a Congressional declaration.
They noted that they had "no idea how (their) son felt about this"...

...and apparently haven't noted that the United States has not had a declaration of war since December 8, 1941; yet we have been engaged in a seemingly endless host of wars, conflicts and "police actions/humanitarian missions in force" since then.
It should also be of some interest that suits of this nature have been filed before, and have been summarily dismissed as frivolous by the courts.
Questions and/or comments, anyone?
