Donald Trump is on a naming spree; Schumer asks Senate to back legal action over partial Epstein files release – key US politics stories from Monday 22 December at a glance

Donald Trump has announced plans for the US navy to build a new generation of warships – known as “Trump-class”.

The ships will be bigger, faster and a hundred times more powerful than any previous US-built warship, the president said on Monday. The project will begin with construction of two such battleships and eventually be expanded to 20 to 25 new vessels.

John Phelan, the navy secretary, added: “Our adversaries will know, when the Trump-class USS Defiant appears on the horizon, American victory at sea is inevitable.”

Past battleship classes were typically named after US states.
