Unlike past events triggered by earthquakes, this tsunami was most likely caused by the collapse of an offshore volcano—Anak Krakatau https://t.co/A9i6vfLYOB

I've always found #volcanoes and #lightning to be fascinating – that #Krakatau/#Krakatoa has been producing volcanic lightning for nearly 24 hours and in these quantities is nothing short of amazing to me. pic.twitter.com/jXo7G1z8ml

Mattis reportedly told the commander of the Strategic Command to keep him directly informed of any event that might lead to a nuclear alert being sent to the president. He even told the commander “not to put on a pot of coffee without letting him know.” https://t.co/lKfhtoDgUQ

One effect of Trump pushing Mattis now: It cuts down opportunities for the secretary to speak in an official capacity.

Mattis was due to testify before both armed services committees in January, and planned to make one last visit to meet with NATO.https://t.co/2qBd3cOGra

Trump hasn’t spoken to Mattis since Thursday. Pompeo called to tell him he was out in a week, per admin official.

Look, I think it's time for some of you folks to get off the ledge about Patrick Shanahan. The man will be Acting SecDef, and it's not the end of the world that he's the one that will do it. Here's a couple of things to think about.

This is amazing. It's as if Mnuchin was trying to create a panic over something nobody was worried about until this release 1/ https://t.co/YJsGnEyOQD

Could saying there's no need to panic when no one is panicking induce a panic?

Trump is venting nonstop about Fed chair Jerome Powell, complaining about stock market and worried about negative indicators — and now Mnuchin is calling the biggest banks for a check-up. He’s worried he is losing his central re-election message. https://t.co/thFn5E0slD

Does anyone feel like the Guardian interview with Corbyn on Brexit has been a turning point? I’ve spent a long time following the peaks and troughs of this movement, and maybe I’m living in an echo chamber, but it does feel like the mood is turning overwhelmingly against him
