Asked on Fox News about the Duchess meeting with Democrat operatives to consider entering politics, Mr Trump said he was “not a fan”.
“Well I hope that happens because if that happened I think I’d have an even stronger feeling toward running,” Mr Trump said.
“I’m not a fan of hers. I think that what she talks about the Royal family and the Queen, and I happen to think, I know the Queen as you know, I met with the Queen and I think the Queen is a tremendous person and I am not a fan of Meghan.”
It followed reports that Ms Markle, 39, was meeting with senior Democratic figures with the view toward a presidential bid.
Mr Trump said his own plans for 2024 will likely not be decided until after the 2022 mid-term elections. When asked directly by “Fox News Primetime” host Maria Bartiromo if he would run again, Mr Trump said he was still considering it without ruling it out.
“Based on every poll they want me to run again but we’re going to take a look and we’ll see,” he said.
Mr Trump then said the first priority the GOP needed to focus on was taking back the House and Senate in 2022.
“Frankly, we’ll make our decision after that.”
