LIBYA -- The Pentagon has ordered two warships to the Libyan coast following the attack in Benghazi that killed Ambassador Chris Stevens and three other American diplomats. One destroyer has already moved to a position off the coast, and another is on the way and should be there within days.

A key U.S. lawmaker says the attack appears to have resulted from a plot and not spontaneous mob violence. House Intelligence Committee Chairman Mike Rogers says the attack was a planned, coordinated and well-executive military-style event.
