President Trump’s staff has learned a hard lesson. If the president says something in private, no matter how geopolitically fraught, it's only a matter of time before he blurts it out in public.
Between the lines: Trump’s Wall Street Journal interview this week is just the latest example of this habit. In that interview, he contradicted the White House's official narrative by saying he had revoked John Brennan’s security clearance because of the Russia probe. It's far from the first time Trump has publicly blurted out something that his aides privately implored him to keep under wraps.
