The special assistant and personal aide to the president is typically referred to as the "body man." In many ways, this person is like an assistant, organizing the president's daily life. Oftentimes, the body man is one of the first people to greet the president in the morning, and he walks the POTUS to the residence at night. The body man often travels with the president, and is also his go-to person if he needs newspapers, briefings, and even pens, according to Politico.
President Trump's first body man, John McEntee, made $115,000 in 2017.
