George Takei says he hopes his lunch date with Donald Trump can help end the billionaire’s opposition to equal marriage, and has revealed that the social conservative recently attended a “beautiful” gay wedding.

Writing on his Facebook page on Tuesday, the gay actor said:

Friends, I had lunch with Donald Trump today at the Trump Tower Grill. It was a lively and engaging hour-long conversation that touched upon his personal position on marriage equality. He confided that he recently attended a same-sex wedding and that he’d found it ‘beautiful’.

I remarked that NY is now a marriage equality state, and that after all, marriage is better for business! Minds are changing across America, and I am always ready to speak to those ready to listen. I hope that my chat with The Don might have some effect on his stance on the subject.

Takei first announced his intention to change the US Apprentice star’s mind last year shortly after appearing on the celebrity version of Trump’s show.

In February, while mulling over a run for the Republican presidential nomination, Trump confirmed he was not in favour of the measure to Fox News.

He said: “I live in New York. New York is a place with lots of gays, and I think it’s great, but I’m not in favour of gay marriage.”

In another interview on Fox News, Trump again said he “didn’t feel good” about it.

Takei, whose best known for his portrayal as Star Trek’s Mr Sulu, has now appeared as himself in an issue of Archie Comics’ series Kevin Keller, which is about a gay teenager living in the fictional town of Riverdale.
