Trump kicked off his official state visit to the United Kingdom with his go-to form of action: insulting tweets. Just ahead of touching down to London, he tweeted out his share of insults for CNN and the Mayor of London, Sadiq Khan. In a tweet this morning, he referred to Khan as a “stone-cold loser”.

.@SadiqKhan, who by all accounts has done a terrible job as Mayor of London, has been foolishly “nasty” to the visiting President of the United States, by far the most important ally of the United Kingdom. He is a stone cold loser who should focus on crime in London, not me......

....Kahn reminds me very much of our very dumb and incompetent Mayor of NYC, de Blasio, who has also done a terrible job - only half his height. In any event, I look forward to being a great friend to the United Kingdom, and am looking very much forward to my visit. Landing now!

Trump, unlike former presidents Bush and Obama, will not be staying at Buckingham Palace due to “ongoing renovations”. At Buckingham Palace, Trump had lunch with the Queen and spent time reviewing a royal collection. Also present were Prince Harry, Ivanka Trump, and Jared Kushner. A state banquet will take place at Buckingham Palace tonight and should bring hundreds of guests, including Prince William, the Duchess of Cambridge, and Prince Harry.

A massive anti-Trump protest is scheduled to take place Tuesday afternoon in Trafalgar Square.
