President Trump’s been in the UK for the meeting of the world’s biggest military alliance, NATO. NATO’s been struggling recently, partly because Trump doesn’t get along so well with America’s traditional allies and now he’s in a row with his own military chiefs. This is because he’s taken decisions without informing them, like pulling out of Syria. And also because they think he doesn’t care about traditional military standards like army discipline. The latest row involves the trial of decorated Navy Seal Eddie Gallagher, who was accused of murdering an Iraqi prisoner. We hear from the BBC’s Whitehouse Correspondent Tara McKelvey about the case find out why Trump has got involved.
