Trump has repeatedly complained about leaks of government information to the press.
Appearing on Fox and Friends on Tuesday morning, Haley called the report "incredibly dangerous" and said it was based on classified information.
That became apparent when the president retweeted a "Fox & Friends" story on USA spy satellites detecting cruise missiles in North Korea.
It's common to cite anonymous officials when reporting on intelligence matters, especially if information is classified. He recently urged Attorney General Jeff Sessions to take a far more aggressive posture toward rooting out leakers.
A new CNN poll shows that a majority (52%) of Americans say Trump's tweets are not an effective way for him to share his views on important issues, and 72% say they do not send the right message to other world leaders.
Police say two were killed in a helicopter crash in Albemarle County
A live stream of the scene posted to Facebook by the Daily Progress shows a massive gathering of police officers around the site. State and local police were responding to a deadly three-car crash at a white nationalist rally earlier this afternoon.
"I can't talk about anything that's classified, and if that's in the newspaper, that's a shame", she said. Word of Trump's carelessness was leaked to the Washington Post by "current and former US officials", and the White House didn't deny that the leak was accurate. "I have no reason to comment on it". "But I will tell you that it's incredibly unsafe when things get out into the press like that". You're not only just getting a scoop on something - you're playing with people's lives.
"If you're think you're getting power or fame from it, all you're doing is putting Americans in danger", she added.
In his very next tweet, Trump was back to blasting Comey - who he had fired one week earlier - for not being tough enough on leakers.
Trump, who receives daily intelligence briefings, would presumably be in a position to know whether USA intelligence officials have reason to believe Kim Jong Un's regime in fact did load cruise missiles onto a patrol boat recently.
