President Trump said he wished Prince Harry “a lot of luck” with his wife Meghan Markle during a press conference. It comes after the Sussexes urged Americans to vote in the upcoming US election.
During the press conference at the White House, a journalist said to Mr Trump: “Prince Harry and Meghan Markle chimed in on the US election and essentially encouraged people to vote for Joe Biden.
“I wanted to get your reaction to that.”
Mr Trump responded: “I’m not a fan of hers, and would say this, and she has probably heard that, but I wish a lot of luck to Harry, because he’s gonna need it.”
The Duke and Duchess of Sussexes made the broadcast from California as part of the Time 100 list on Wednesday.
Prince Harry told US citizens to “reject hate speech” during the announcement.
He said: “When the bad outweighs the good, for many, whether we realise it or not, it erodes our ability to have compassion and our ability to put ourselves in someone else’s shoes.
“Because when one person buys into negativity online, the effects are felt exponentially. It’s time to not only reflect, but act.”
Prince Harry is not actually eligible to vote in the US and has never voted for an election in the UK due to traditions upheld by the Royal Family.
They said: “The political arena is very sensitive for all members of the Royal Family.
“You cannot have an apolitical institution, which is what a hereditary monarchy is, and have members of the royal family making even slightly political comments.
“Courtiers would be extremely concerned that if they are going to continue to comment on what could be the most contentious US presidential election in living memory, how difficult could that get?”
But Buckingham Palace has refused to comment on the Sussexes’ broadcast.
A spokesman for the palace said: “We would not comment. The Duke is not a working member of the Royal Family and any comments he makes are made in a personal capacity.”
The US presidential election vote is set to take place on 3 November.
A royal expert advised that the Sussexes should detach themselves from the Royal Family completely to avoid confusion.
Royal biographer Robert Jobson told the MailOnline that it “may be easier” if the Sussexes give up their royal titles due to the “business and political agenda they appear to want to pursue”.
Royal Family members are traditionally not supposed to comment or get involved in politics.
Mr Jobson added: “Frankly, I think it would be better for Harry to withdraw, along with his son, from the line of succession to avoid further confusion.”
