A spokesman for British Prime Minister Theresa May said early Friday that senior United Kingdom officials had protested to the Trump administration about Spicer's comments.
He said allegations that British spies had helped Barack Obama eavesdrop on Mr Trump during the presidential campaign - cited by the White House press secretary - were "ridiculous".
"He didn't use the NSA, he didn't use the Central Intelligence Agency, he didn't use the Federal Bureau of Investigation, and he didn't use the Department of Justice", Napolitano said, claiming that Obama used Britain's GCHQ to circumvent USA law.
During a media briefing at the White House, presidential spokesman Sean Spicer drew reporters' attention to comments made earlier this week on Fox News TV by former judge Andrew Napolitano in relation to Mr Trump's controversial claim that wiretaps had been installed at his NY residence.
In recent days, Trump and his aides have attempted to redefine the president's claims, saying that his use of the wiretapping term covers a variety of surveillance techniques.
In a rare public statement, the GCHQ, Britain's equivalent of the U.S. National Security Agency which monitors overseas electronic communications, said the claims should be ignored. "This is Nixon/Watergate. Bad (or sick) guy!" the president posted once again, stressing his claims.
Other White House officials, who also requested anonymity, said Spicer had offered no regret to the ambassador. "Apparently there is no evidence of proof or any basis in fact so I think you should simply retract it".
Furthermore, the controversial statement spiraled out of control after Sean Spicer said that Obama did not use the CIA, FBI or NSA to wiretap Trump's phones but instead, requested the services of GCHQ.
Ranking member Rep. Adam Schiff, a California Democrat, said he was "absolutely confident" the DOJ report would not back up Trump's allegation.
On Friday, Trump said questions on this should be asked of Fox News, not him.
Prior to receiving the classified documents from the DOJ, both Nunes and Schiff had already stated flatly that Trump Tower was clearly not wiretapped.
Without providing evidence, Donald Trump has accused his predecessor Barack Obama of bugging his hotel during last year's elections.
Even in the face of flat denials by top officials in the Obama administration, who were in a position to know, Trump has stuck to his incendiary claim that the former president personally ordered a tap on his phones.
A White House official confirmed that Darroch and the British prime minister's national security adviser, Mark Lyall Grant, expressed concerns to Spicer and to Trump's national security adviser, H.R. McMaster.
GCHQ was the first agency to warn the U.S. government, including the National Security Agency, that Russian Federation was hacking Democratic Party e-mails during the presidential campaign.
Meanwhile, the Senate Intelligence Committee said, March 16, there was no evidence to support Trump's claim.
