My God, is the inauguration really this month? How quickly time passes. But also how everything sort of stays the same. For example, Donald Trump using Twitter like his diary. Back in October 2016, The New York Times compiled this complete list of 282 people, places, and things that Trump has insulted on Twitter. Each insult is directly linked to a Tweet of his (if it's deleted, you can look for it on his Twitter archive).
Just remember, for the next 4 years, Trump isn't tweeting for you. He's tweeting for himself.
