This Week, US Republican Rand Paul addressed the Senate for thirteen hours - a mammoth attempt - ostensibly, to block the approval of President Barack Obama's pick to head the CIA.

It is estimated to have killed thousands in countries like Pakistan and Yemen. Now several other appointments will have to be considered by Congress.
