Donald Trump has deflected questions about allegations GCHQ spied on him, saying he was just repeating somebody else's claims.
In a joint news conference with German Chancellor Angela Merkel, the US President was asked whether he regretted tweeting the claim that the Obama administration had wiretapped Trump Towers during the election.
In his reply, he made a reference to claims that Mrs Merkel had been the subject of surveillance by Mr Obama in 2010 and appeared to lay the blame for the original allegation on Fox News.
He said: "As far as wiretapping (gesturing to Mrs Merkel), this past administration, at least we have something in common perhaps.
"We said nothing - all we did was quote a certain very talented legal mind who was the one responsible for saying that on television. I didn't make any opinion on it.
"That was a statement made by a very talented lawyer on Fox and so you shouldn't be talking to me, you should be talking to Fox, ok?"

Those comments appear to contradict a series of tweets by the US President earlier this month, in which he labelled former president Barack Obama a "bad (or sick) guy" and said a "good lawyer could make a great case" out of the claims.
Mr Trump was referring to US media commentator Judge Andrew Napolitano, who made the original accusation about GCHQ involvement on Wednesday.
That claim was then repeated by White House press secretary Sean Spicer, who has repeatedly said the US President stands by the allegation and does not regret making it.
On Thursday, US Congress rejected the wiretap claim, with leaders of the Senate Select Committee on Intelligence saying: "Based on the information available to us, we see no indications that Trump Tower was the subject of surveillance by any element of the United States government either before or after Election Day 2016."
GCHQ had previously dismissed the wiretap as "utterly ridiculous".
A spokesman for Prime Minister Theresa May said on Friday that the White House had assured Number 10 it will not repeat the GCHQ claims .
He said: "We've made clear to the administration that these claims are ridiculous and they should be ignored and we've received assurances that these allegations will not be repeated.
"We have a close relationship with the White House and that allows us to raise concerns as and when they arise as was true in this case."
The US Justice Department said it had delivered documents to congressional committees following their request for information on the wiretapping allegations.
Mrs Merkel and Mr Trump appeared to have an awkward meeting at the White House, with the US President seemingly refusing to shake the German Chancellor's hand in front of the media in the Oval Office.
They had, however, shaken hands when they met earlier.
The two leaders discussed NATO funding, trade agreements and the international situations in Ukraine and Syria.
But Mr Trump denied claims his policies were isolationist. He said: "I don't believe in isolationist policy, but I also believe that a trade policy should be fair.
"I am a free trader, but I'm also a fair trader."
