The Wikipedia entry for the Korean War mentions Congress allocating money for the war effort within the month after US got involved. That certainly appears to be Congressional approval.
And the US response was after a UN resolution calling for it, giving some legitimacy

Corrected. Thanks.
Does a formal declaration of war matter?
