David [Cameron] has been an outstanding friend and partner on the global stage and, based on our conversation, I'm confident that the UK is committed to an orderly transition out of the EU.

In Europe, where the terrorist threat is probably greatest at the moment, the amount of information-sharing that's been taking place, the effectiveness of law enforcement across borders gives us the ability to protect ourselves while still being true to the basic precepts of our liberal democracies.

The most powerful political moments for me come when I feel like my actions are aligned with a certain truth. I can feel it. When I'm talking to a group and I'm saying something truthful, I can feel a power that comes out of those statements that is different than when I'm just being glib or clever.
