Lunch at Buckingham Palace must have been pretty interesting Monday with Prince Harry joining Queen Elizabeth and other royal family members for a meal with President Donald Trump, who falsely insisted Sunday that he never called Harry’s wife, Meghan Markle, “nasty” in an interview last week.

It’s not known what happened at the lunch — because reporters were not present — and whether Harry and Trump exchanged pleasantries, or Trump even addressed the controversy that arose of her “nasty” remark.

Queen Elizabeth hosted the lunch in honor of the president and first lady’s state visit to the United Kingdom. Prince Charles, his wife Camilla and White House senior advisors Ivanka Trump and Jared Kushner also were present at the lunch.

Harry “noticeably hung back” when the queen led the group into the palace’s picture gallery, where she showed the president and first lady a collection of artifacts, including the Declaration of Independence and portraits of George Washington and George III, according to a tweet from Emily Andrews, the royal correspondent for The Sun.

If Harry interacted with Trump family members, it was with Trump’s daughter Ivanka. He entered the gallery with her, though he then “drifted off” to talk to the Lord Chamberlain, according to Andrews. Vanity Fair, citing a report from CNN, said that Harry might have been included in the lunch as a courtesy to Melania Trump to thank her for leading the US team to the Invictus Games in Toronto in 2017.

He walked in with Ivanka (was he supposed to show her round the exhibition?? or maybe they sat next to each other at lunch) and then drifted off to talk to the Lord Chamberlain (the Earl Peel). pic.twitter.com/NLyfNvkZx6 — Emily Andrews (@byEmilyAndrews) June 3, 2019

Earlier in the day, Trump and the first lady arrived by Marine One helicopter at Buckingham Palace, where they were first greeted by Charles and Camilla, then by Queen Elizabeth.

For the ceremonial welcome, Charles invited Trump to inspect the guards before the group slipped inside to sit down for lunch, CNN reported. Ivanka Trump and Jared Kushner were spotted earlier watching the president’s arrival at Buckingham Palace.

Meghan was not scheduled to be at the palace event; she’s on maternity leave after giving birth to son Archie on May 6.

The Duchess of Sussex’s absence probably saved the royal family from a potentially awkward encounter, even if things were not awkward enough for her husband being at the lunch.

“Harry might just take the opportunity to take his revenge and have it out with the President,” Tom Newton Dunn, political editor of The Sun, told CNN. But, Dunn added, “I suspect he won’t,” noting that the royals are used to keeping their feelings to themselves.

Trump also had made lewd comments about Harry’s mother, Princess Diana, in a radio interview with Howard Stern in 1997, the year she was killed in a Paris car crash. Trump agreed with Stern’s comment that he could have “nailed” Diana.

This lunch that included Harry and Trump comes after the president called Meghan “nasty” in an interview last week.

Trump was recorded, using this word to describe the U.S.-born duchess, after apparently learning that she had called him “divisive” and “misogynistic” during the 2016 election.

“I didn’t know that,” Trump said in an interview with The Sun. “What can I say? I didn’t know that she was nasty.”

The former TV actress made her critical comments about Trump in a May 2016 interview before she had met and started dating Prince Harry.

Trump’s reference to the duchess as “nasty” sparked a debate in the United Kingdom and stayed in the news over the weekend after Trump insisted in a tweet Sunday that he never called her this word.

“I never called Meghan Markle ‘nasty.’ Made up by the Fake News Media, and they got caught cold!”

But as numerous outlets have pointed out, The Sun released audio of the interview.

Trump previously used the word to describe Hillary Clinton during a 2016 presidential debate, calling his Democratic opponent a “nasty woman.” As the Washington Post pointed out, the word later became a rallying cry for feminists and those in the anti-Trump movement, say the president’s use of the word is part of a pattern for how he attacks his female critics.

In Britain, the debate over the “nasty” comment brought up other ongoing concerns about Meghan, according to the Post. The concerns have to do with if and how her past political activism could make things awkward for the royal family. Members of the royal family are not supposed to publicly voice political views.

Meghan began speaking out against sexism as a child and was open about her views on politics, race and gender equality when she was starring on the TV show “Suits.” She has called herself a “proud” feminist who spoke about her commitment to gender equality at a United Nations conference on International Women’s Day 2015. She also served as a U.N. Women’s Advocate for Political Participation and Leadership.

During a 2016 interview on “The Nightly Show with Larry Wilmore,” Meghan was asked what she thought of a potential Trump presidency.

“It’s really the moment that I go, we film ‘Suits’ in Toronto and I might just stay in Canada,” Meghan said. She continued: “Yes, of course Trump is divisive. Think about just female voters alone. … I think it was in 2012, the Republican Party lost the female vote by 12 points. That’s a huge number and with as misogynistic as Trump is and so vocal about it, that’s a huge chunk of it.”

Meghan also indicated her support for Clinton, and not just because she’s a woman. “Trump has made it easy to see that you don’t really want that kind of world that he’s painting,” Meghan said.
