““The first big lesson that Corey learned about his new boss was that Donald Trump practically lived on his phone, a big black landline at the left-hand corner of his desk. In the early days, every time Corey walked into Trump’s office, he seemed to be on the phone with some titan of industry or celebrity. One day early on when he walked in, Trump was on the phone with former president Bill Clinton, having a lengthy conversation with him. Trump also used the phone to manage his organization. The lesson was that if you worked for Donald Trump, you better have your phone on, because he was going to call.””
