You may have heard that when you abandon #Twitter, it's recommended to leave your account intact and just stop using it, instead of deleting it. Here's a good example of why that's suggested.
Judge Juan #Merchan's daughter deleted her Twitter account last year (presumably after a prior round of threats and unwanted publicity). That made her old username available -- someone has since registered it, and is posting things that #Trump is using to rile up his base.
