"There's a fringe narrative out there that the USA and United Kingdom and all these other governments are willy-nilly just exploiting every vulnerability in every device they can in order to gather information into a big pile and then root through it for interesting things", he said.
And on Friday Fox News anchor Shepard Smith said Fox News "no evidence" that the president was surveilled and can not confirm Fox News analyst Judge Andrew Napolitano's "commentary" about the British spy agency.
Spicer quoted Napolitano's comments as part of a lengthy citation of media reports made in response to questions from reporters about the statement by Burr and Warner.
He was asked about Mr Spicer's comments on GCHQ at a press conference yesterday after a meeting with Angela Merkel.
"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?"
The Department of Justice said it has complied with a request from the House Intelligence Committee to turn over any relevant material related to President Donald Trump's claim that he had his "wires tapped" before the election.
"A president only has so much political capital to expend and so much moral authority as well, and so any time your credibility takes a hit, I think in many ways it weakens the officeholder", Dent said.
USA ties with Germany were frayed by news reports in 2013 citing leaked intelligence documents that Washington had bugged Merkel's mobile phone.
Klopp confident in Firmino recovery for City clash
Man City will be looking to rebound from their mid-week Champions League tie with Monaco that ousted the Citizens from that competition.
A White House official told CNN earlier Friday that national security adviser H.R. McMaster spoke with his British counterpart Thursday after Spicer cited the Fox News report. Officials have said Trump didn't necessarily mean Obama personally ordered the surveillance; that wiretapping could refer to a broad range of surveillance efforts; and that the effort may not have specifically targeted Trump Tower in NY, which houses Trump's business headquarters and home.
Republicans in Congress also said Trump should retract his claims.
Last week, Judge Napolitano wrote a column detailing how former president Obama could have spied on candidate Trump without probable cause or a warrant - contradicting the liberal media narrative that the president needs authorization to spy on someone.
On Friday, Fox News anchor Shepard Smith said on the air that "Fox News can not confirm Judge Napolitano's commentary. Fox News knows of no evidence of any kind that the now President of the United States was surveilled at any time, in any way, full stop", Smith said.
The British MP who now chairs Parliament's Intelligence and Security Committee issued a statement today knocking down Napolitano's theory.
He added that allegations that British intelligence had aided Obama in an off-the-books espionage effort were "utterly ridiculous and should be ignored".
Reuters reported earlier this week that an unidentified British security official had denied the allegations about Trump. It's the initials for the British intelligence spying agency.
