Trump hails American military might at USS Gerald R Ford commissioning

US president Donald Trump has declared that the most advanced aircraft carrier to join the US Navy, the USS Gerald R Ford, will cause America's enemies to "shake with fear" whenever they see it.

Mr Trump gave a speech at the commissioning ceremony for the 100,000-tonne, 12.9 billion dollar (£9.9 billion) warship, in which he praised the US military and the American labour that went into building it.
