Talking of the Senate.

I seem to recall that there was a Senate scene which took place straight after the assassination attempt at the beginning of AOTC.

Palpatine prematurely announces that Padme was killed, only to have her turn up and interupt the call to vote for the formation of an army with her objections.

Did I imagine this, was it filmed but not used or was it written but not filmed?

I know it didn't turn up on the deleted scenes on the DVD but there was a lot of material that has never seen the light of day like the forementioned Threepio getting his coverings scene.
