Q&A: Trump, Ukraine and the Whistleblower Associated Press WASHINGTON - Very behind the scenes, a whistleblower from the intelligence community voiced urgent concern about a matter involving a conversation between Ukraine's leader and President Donald Trump. It's so hush-hush that even Democrats won't say all that they know, or suspect. Very much out in the open, Trump is calling for an investigation that involves Ukraine and could help him win re-election if it breaks his way. Trump's interest in getting dirt from abroad on prospective Democratic presidential rival Joe Biden has been hiding in plain sight for months. His fealty to standards that other presidents have either lived by or pretended to -- as when it comes to chats with foreign leaders, for example -- is thin. This is, after all, the man who openly encouraged Russia to snoop on Hillary Clinton's email and much more recently said that, sure, he'd listen to foreigners who come to him with dirt on an opponent. Why not? he wondered. As the contours of the episode roiling the capital begin to flesh out, here are some questions and answers at the intersection of Trump, Ukraine and the whistleblower. Why the whistle? Because someone in the government, who is under the umbrella of U.S. intelligence, saw or heard something that raised a credible and "urgent concern" about how someone else in government did or said something that "involves confidential and potentially privileged communications by persons outside the intelligence community." That's according to Michael Atkinson, the inspector general for intelligence. It's no more spelled out than that so far, because the complaint remains a closely held secret. .
