A sweeping Defense Department review ordered by President Trump has identified roughly 300 gaps in weapon-makers’ supply chains that could threaten U.S. military campaigns if they’re not corrected, a senior administration official said Thursday.

The report, commissioned in July 2017, will be presented to Trump on Friday, and the president is expected to earmark funds available through both the Defense Production Act and a 1939 defense stockpile program to address some of them, the official said.
