Valid point. I guess we can wait and see if the Trump administration continues to point the finger at GCHQ. If not, I'd say that's pretty good evidence that it report is true, given how infrequently Trump and his people walk back or drop a claim.
Right, it goes both ways. Trump based his tweet on Fox News reporting from an anonymous source. The Telegraph is reporting from an anonymous source. Do you believe both of them?
GCHQ has now made a public statement, so the Telegraph was correct. It isn't in the habit of publishing made-up bullshit (aka fake news). Fox, on the other hand...
Intelligence sources told The Telegraph that both Mr Spicer and General McMaster, the US National Security Adviser, have apologised over the claims. "The apology came direct from them," a source said.
It's based on an anonymous source.
Here's another quote from that same article:
"Three intelligence sources have informed Fox News that President Obama went outside the chain of command - he didn't use the NSA, he didn't use the CIA, he didn't use the FBI and he didn't use the Department of Justice - he used GCHQ."
So we're going to discard what several anonymous sources said, but we will believe what some other anonymous source said?
