Responding to reports that the couple has moved to California, Trump tweeted on Sunday: “I am a great friend and admirer of the Queen & the United Kingdom. It was reported that Harry and Meghan, who left the Kingdom, would reside permanently in Canada. Now they have left Canada for the U.S. however, the U.S. will not pay for their security protection. They must pay!”

Harry —grandson of Queen Elizabeth II and sixth in line to the British throne — married the American actress Meghan Markle at Windsor Castle in May 2018, in a ceremony watched by millions around the world.

But the couple later said they found scrutiny by the British media — which they said tipped into harassment — intolerable.
