I'M PRETTY SURE THAT'S NOT HOW SEPARATION OF POWERS WORKS:

White House provides plane to senator for key stimulus vote (CNN, 2/13/09)

The plane is being provided by the White House, Brown's office said, because the vote is considered "official business," and there are no commercial flights available that would allow him to cast the vote and return to Ohio for his mother's funeral Saturday morning.

A White House official refused to provide a cost estimate for the military plane, but acknowledged "it will be a higher cost than if he were flying commercial."
