Piers Morgan, who interviewed the US President, tweeted Trump had "publicly apologised for retweeting far-right group Britain First".
Trump's "know nothing" answer strained credulity.
So did Trump actually apologize?
The retweets caused British Prime Minister Theresa May to put out a statement saying, "It is wrong for the president to have done this", which Trump later responded to on Twitter, as he is wont to do.
Some Britons are angry at the prospect of a visit by Trump with large protests expected when he does arrive, most probably in the second half of the year according to a senior British government source.
'I don't know who they are, I know nothing about them, so I wouldn't be doing that.
"Says the world's biggest liar and self-appointed "least" racist person you'll ever meet", added another about Trump's responses.
"Radical Islamic terror, whether you like talking about it or not, you look at what's going on in the United Kingdom, you look at what's going on all over the world", he told Good Morning Britain's Piers Morgan.

A German far-right politician resigns after converting to Islam
A high-ranking official in an anti-Muslim political party in Germany has shocked observers by converting to Islam himself. He told the German newspaper Tagesspiel that his conversion was "my business", refusing to comment beyond that.
The president caused widespread outrage in the United Kingdom and prompted a rare rebuke from British Prime Minister Theresa May in November after he shared the videos, which purported to show violent acts committed by Islamic extremists.
The video showed alleged Muslim migrants purportedly thrashing a disabled Dutch boy. The fact that the videos were sketchy or fake doesn't really matter to Trump - because they show what he already believes to be true.
The internet went ablaze, with even Piers himself asking Trump to "stop this madness."
He said: 'I know nothing about them and I know nothing about them today.
"They had a couple of depictions of radical Islamic terror", Trump said.
Morgan and Trump became friends while the former News of the World editor, who was working at CNN at the time, after he won the US' Celebrity Apprentice. Sadiq Khan, the mayor of London, tweeted that "Britain First is a vile, hate-fuelled organisation whose views should be condemned, not amplified" and called on May to "cancel her ill-judged offer of a state visit to President Trump".
Late last November White House press secretary Sarah Sanders said that the president doesn't check everything that he tweets but that he "knew what the issues are".
Trump said "I don't want to cause any difficulty for your country" when Morgan pressed him on whether he would apologize.
