The first lady’s spokeswoman, Stephanie Grisham, said that the procedure was successful and that there were no complications. 

Grisham said Trumpis at Walter Reed National Military Medical Center just outside Washington and will likely remain there “for the rest of the week”.

Donald Trump tweeted in the early evening that his wife was in good spirits and that he was on his way to visit her.

Last week, after rarely putting herself in the public eye other than in roles directly supporting her husband’s work, the first lady launched her “Be Best” initiative to help children counter bullying. The initiative was aimed particularly at online bullying and encouraged children to behave with more consideration and kindness on social media platforms, although the accompanying literature ran into a plagiarism kerfuffle. She had previously won praise for hosting a lavish dinner at the White House for the state visit by Emmanuel Macron, France’s president.

A statement was put out by the White House on Monday afternoon, saying: “This morning, First Lady Melania Trump underwent an embolization procedure to treat a benign kidney condition. The procedure was successful and there were no complications.”

It continued that Melania Trump was at Walter Reed “and will likely remain there for the duration of the week. The first lady looks forward to a full recovery so she can continue her work on behalf of children everywhere.”
