He did. I don't know if he writes his tweets alone but although I hate this social media culture, I love how he can trigger the left with a note, sometimes to his advantage. When all that 'go home' outrage, he modified the asylum policy and the media basically ignored them. I hate sleazy politics but it's interesting watching Trump when the most powerful man in the world, apparently, has been so mercilessly, and mostly unfairly, reacts.
