The aircraft carrying the 52 American hostages had cleared Iranian airspace on the first -- first leg of a journey home. And at every one of the 52 hostages was alive, was well and free.

I fear for our democracy.

Without immediate action, we are at genuine risk of civil conflict and losing our precious democracy.

All of us must learn to waste less energy.
