It has been reported by the Washington Post that United States President Donald Trump allegedly revealed classified information about Isis to the Russian foreign minister during a White House meeting last week.
The information was reportedly revealed by the President in the Oval Office, and was said to have been provided to the US by an American ally through a sensitive intelligence sharing arrangement.
H.R. McMaster, the national security adviser, said in a brief statement that the story was "false":
The president and the foreign minister reviewed common threats from terrorist organizations to include threats to aviation.
At no time were any intelligence sources or methods discussed, and no military operations were disclosed that were not already known publicly.
He later said:

I was in the room. It didn't happen.
Senior Republican senator John McCain said the allegations were "disturbing" if correct:

The story has been interpreted by the media as indicative of a White House that cannot control the incompetent disclosures and boasting of its President.
