You're right, but the Constitution doesn't allow you to selectively enforce it. That's why our nation has survived this long. The rules apply to everyone.
Court decisions to date have tended to side with Bush's position here - that intelligence is an executive function and the Legislative has limited power to intrude on that function.
The key recourse for the Legislative would be to impeach and remove a president who abused these powers for political purposes - they have little say in regulating the use of the powers.
Clinton should have been impeached and removed for the FBI Files.
I have seen nothing, however, that shows Bush has abused his powers.
