By the numbers: Defense spending

A battle is brewing in Washington over military and defense spending.
The GOP-controlled House of Representatives on Friday passed a nearly $643 billion military spending bill -- a measure at odds with prior defense spending agreements and President Barack Obama's Pentagon plans.
