Bush's legal team has given their OPINION. Its the duty of congress (and they don't need 60%...just that razor thin majority") to force this into the Courts. Of course, that means that they will have to do SOMETHING other than pass non binding resolutions and >threaten< contempt.
That would be a step in the right direction, but a far to slow one. Taking it to court now will mean Bush can simply run out the clock. Congress really needs to take a step towards impeachment.
