Trump also said he looks forward to visiting Britain - where he has been invited sometime for a state visit to be hosted by the Queen - and apologizes for retweeting videos by a far-right group in Britain, which exacerbated tensions with May and drew complaints in the United Kingdom parliament.
In an excerpt of an interview with Piers Morgan for ITV, aired earlier today on Good Morning Britain, the former CNN host challenges Donald Trump for his retweet of debunked videos that purportedly depicted radical Islamist terror, which originated with an extremist group called Britain First. "If you're telling me they're terrible racist people, I would certainly apologize if you would like me to do that", he said, referring to the creators of the videos.
Asked about opposition to his state visit by Labour leader Jeremy Corbyn, Mr Trump is quick to say "I don't know the man".
Trump was less apologetic about tweeting the content of the unverified videos, saying he was a "big believer in fighting radical Islamic terror".
Piers Morgan shared the news that Trump is not a feminist in a tongue-in-cheek Tweet saying, "Massive global outrage & mockery over President Trump telling me he's not a feminist". Asked by Morgan whether he cared if British people disagreed with his views, Trump said: "I don't care".
"She's been doing a very good job".
Piers also tweeted a picture of himself with Donald Trump, revealing that the full chat will air on ITV on Sunday at 10pm. I mean, if they don't, I could very nicely stay home. "They look like a lovely couple".
In the interview, Trump said he believed the European Union had "very, very unfair" to the United States and it would be to the group's "detriment".
The trip has been delayed, however, and in Trump recently pulled out of a plan to open the new USA embassy in London, a move British officials blamed on threats of mass protests.
Trump's mother Mary Anne MacLeod was born on the Isle of Lewis and he briefly visited the house where she grew up in Tong in 2008.
"President Trump has declared he is NOT a feminist", Morgan wrote.
"I don't know who they are, I don't know [anything] about them, so I wouldn't be doing that", Trump said. "I'm for women, I'm for men, I'm for everyone".
