Department of Homeland Security Secretary John Kelly told Meet the Press' Chuck Todd on Sunday that high-level classified leaks, like those over the Manchester attack in the U.K., are "borderline treason."

"I don't know where the leak came from. But I... immediately called my counterpart in the UK.... She immediately brought this topic up. And, if it came from the United States, it's totally unacceptable. And I don't know why people do these kind of things, but it's borderline, if not over the line, of treason."

He added:

"I believe when you leak the kind of information that seems to be routinely leaked — high, high level of classification — I think it's darn close to treason."

Shortly after Kelly's appearance on Meet The Press, President Trump took to Twitter once again, making it clear how he feels...

British Prime Minister May was very angry that the info the U.K. gave to U.S. about Manchester was leaked. Gave me full details! — Donald J. Trump (@realDonaldTrump) May 28, 2017

One wonders if this 'excuse' to really go after intel leakers will finally slow down the 'sources' (real or fake) behind so many WaPo, CNN, NYT stories?
