From The Washington Post:
President Trump revealed highly classified information to the Russian foreign minister and ambassador in a White House meeting last week, according to current and former U.S. officials, who said Trump’s disclosures jeopardized a critical source of intelligence on the Islamic State.
The information the president relayed had been provided by a U.S. partner through an intelligence-sharing arrangement considered so sensitive that details have been withheld from allies and tightly restricted even within the U.S. government, officials said.
The partner had not given the United States permission to share the material with Russia, and officials said Trump’s decision to do so endangers cooperation from an ally that has access to the inner workings of the Islamic State. After Trump’s meeting, senior White House officials took steps to contain the damage, placing calls to the CIA and the National Security Agency.
“This is code-word information,” said a U.S. official familiar with the matter, using terminology that refers to one of the highest classification levels used by American spy agencies. Trump “revealed more information to the Russian ambassador than we have shared with our own allies.”
In their statements, White House officials emphasized that Trump had not discussed specific intelligence sources and methods, rather than addressing whether he had disclosed information drawn from sensitive sources.
Just to underline that last point: The Washington Post reported Trump revealed intelligence from a secret source, not that Trump revealed the source itself.
Remember, this was the meeting that Trump allowed a Russian state news organization to be present and take photos, but no U.S. media outlet.
You may recall Trump turned the entire presidential election into a referendum on Hillary Clinton’s handling of “unmarked,” low-level classified info.
Let’s take a trip on the way-back machine:
Crooked Hillary Clinton and her team “were extremely careless in their handling of very sensitive, highly classified information.” Not fit!

The real story that Congress, the FBI and all others should be looking into is the leaking of Classified information. Must find leaker now!
