United States President Donald Trump has invoked the Defence Production Act to address constraints in the production of munitions, according to a presidential memo, CBS News reports.

According to the report, the memo delegates the defence secretary to use the Defence Production Act, which can be used to jumpstart production of key items.

“The memo says the mechanism is warranted because fragile supply chains and production bottlenecks may ‘impair the ability’ for the US to expand the availability of munitions, missiles and equipment required for the national defence,” the report said.
