For all the outrage over what President Trump might have told the Russian ambassador last week, aggressive journalism — and ambitious leaks — may have done the worst harm on Tuesday.

Monday’s stories on what Trump told his Russian guests noted that he’d given details that might help them figure out how Washington had gotten the intel.

But the New York Times reported Tuesday that Israel was the source.

And then ABC disclosed even more sensitive specifics: An Israeli spy inside ISIS had uncovered the active plot to bring down a US-bound jet with a laptop bomb able to evade airport security.

This info is said to have been provided on condition that Washington not reveal who came up with the goods. And we’d like to hope that the leaks to the Times and ABC are disinformation to obscure the true source.

National security adviser H.R. McMaster insists Trump didn’t even know where it came from.

So why did the Times and ABC feel compelled to publicly disclose more details? Maybe the Russians hadn’t figured it out — yet now the whole world knows.

ABC went live with info that, by its own admission, places the life of the Israeli spy “at risk.” So ISIS knows now — thanks more to the US media than to the president.
