"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.
General McMaster contacted Sir Mark Lyall Grant, the Prime Minister's National Security adviser, to apologise for the comments. Mr Spicer conveyed his apology through Sir Kim Darroch, Britain's US ambassador."
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?
