Very Stable Genius Donald Trump responds to London Mayor Sadiq Khan’s brutal takedown with the “best words” possible: “You’re a stone cold loser, nasty and half Bill de Blasio’s height.”

Trump melted down on Twitter: “@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!”

The dude who likes to brag that he’s really smart and has the best words had the weakest comeback possible.

Khan wrote in brutal op-ed in the Guardian: “The deliberate use of xenophobia, racism and “otherness” as an electoral tactic. Introducing a travel ban to a number of predominately Muslim countries. Lying deliberately and repeatedly to the public.”

“No, these are not the actions of European dictators of the 1930s and 40s. Nor the military juntas of the 1970s and 80s. I’m not talking about Vladimir Putin or Kim Jong-un. These are the actions of the leader of our closest ally, the president of the United States of America.”

“Donald Trump is just one of the most egregious examples of a growing global threat. The far right is on the rise around the world, threatening our hard-won rights and freedoms and the values that have defined our liberal, democratic societies for more than seventy years.”

Um, England, we didn’t send you our best this morning.
