US and UK are both five eyes countries. They share intelligence regarding communications with Russia.
Okay... Now, the UK can intentionally spy on a US citizen and share that data with the US Intelligence agency, which circumvents laws preventing each agency from spying on its own citizens. (We, as citizens, have little oversight that this does not happen.)

I'm not sure why the White House had to "apologize" -- If you watched the Press Briefing from yesterday, Spicer spent about 10 minutes reading various news articles snippets since January 20th "wiretapping" NYT headline. He mentioned the Fox News/Nepolitano story, not exactly endorsing the story itself but showing the breadth of 'sources' and the media's response. Just set up a timeline for the journalists who were acting like they had all the answers.
I can post the entire Press Briefing on here if you guys would like to refute.
