It's implicitly "President Trump was briefed and took no action yet."
You don't write about it in the NYTimes unless there's a purpose. That purpose is leverage. If you're negotiating, you don't blow all your leverage upfront; you subtly let the other party know you have it, and then wait to see if they play ball. If they don't, that's when you apply pressure.
Another interpretation is that someone in the intelligence community felt that since Trump was ignoring what they perceived to be a serious threat to security, their best recourse was to use the media to raise an alarm.
It's not the NYT but the NY Post, Rupert Murdoch tabloid media.
