White House press secretary Sean Spicer then quoted Napolitano's remarks about GCHQ Thursday while defending Trump's assertions that Obama wiretapped him previous year.
The British press reported Friday morning that Trump's national security adviser had himself apologized to the British government for the allegation.
"All we did was quote a certain very talented legal mind who was the one responsible for saying that on television", Trump said, referring to analyst Andrew Napolitano.
The ministers were forced Saturday to leave out an entire section related to the Paris accord on combating climate change after US Treasury Secretary Steven Mnuchin said green issues were "not in my track".

Republicans in Congress also said Trump should retract his claims.
The president and German chancellor have had a tense history.
In a photo op after their Oval Office meeting, the two leaders sat next to each other in separate chairs.
She said she aims to do the same for Germany, but takes a different approach.
Trump is more outspoken and improvisational and has little time for diplomatic niceties.
Observers on both sides of the Atlantic say this visit is a good precursor for other meetings they'll have at other worldwide summits later this year. Other reports indicate that USA intelligence had been listening in on her phone as along ago as 2002, when she was leader of the German opposition.
