Not that he had his marbles to begin with . . .

. . . but retweeting the Britain First hate videos was batshit insane. Theresa May rather awkwardly find herself in Amman, Jordan as this is going on, where she had this to say:

The fact that we work together does not mean that we are afraid to say when we think that the United States have got it wrong and to be very clear with them. I am very clear that retweeting from Britain First was the wrong thing to do. Britain First is a hateful organisation. It seeks to spread division and mistrust in our communities. It stands in fundamental opposition to the values that we share as a nation – values of respect, tolerance and, dare I say it, common decency.

So what does that say about Twittler? And here's Kim Darroch, Britain's ambassador to the United States:

British people overwhelmingly reject the prejudiced rhetoric of the far right, which seek to divide communities & erode decency, tolerance & respect. British Muslims are peaceful and law abiding citizens. And I raised these concerns with the White House yesterday.

Here's Labor MP Stephen Doughty:

This is the president of the United States, sharing with millions inflammatory and divisive content, deliberately posted to sow hatred and division by, as the home secretary says, a convicted criminal who is facing further charges and who represents a vile fascist organisation seeking to spread hatred and violence in person and online. By sharing it, he is racist, incompetent or unthinking – or all three.

Britain First says it has received hundreds of membership applications  as a result of the "president's" action.

Here's what Mitch McConnell has said about it:

And here is Paul Ryan's response:

Update: I'll just add this from Michelle Goldberg:

If you think 2017 was bad, imagine an America without allies fighting another two-front war, this one involving nuclear weapons, under the leadership of the most hated president in modern history, while a torture apologist runs the C.I.A. The world right now is a powder keg. Trump, an untethered maniac, sits atop it, flicking a lighter that Republicans in Congress could take away, but won’t. If everything goes up in flames, we can’t say we weren’t warned.
