The article text supplied for this piece does not actually contain the story itself — only the Daily Mail's site navigation, menu links and a list of unrelated headlines from elsewhere on the site. No details about the "extraordinary intervention" by Donald Trump, the aide involved, or the alleged security leak are present in the text provided, so a substantive summary cannot be produced from this content.

Based on the headline alone, the piece appears to concern a security breach involving a female aide close to Donald Trump, whose "dangerous" secret was reportedly exposed, prompting a personal intervention from Trump. However, without the actual article body — including who the aide is, what the leak revealed, or what action Trump took — no further factual details can be reliably summarised in British English.
