President Trump reportedly has a 'longtime fear of being poisoned'

President Donald Trump allegedly has a "longtime fear of being poisoned," according to an excerpt from Michael Wolff's 'Fire and Fury: Inside the Trump White House' published Wednesday.

"Trump, in fact, found the White House to be vexing and even a little scary. He retreated to his own bedroom—the first time since the Kennedy White House that a presidential couple had maintained separate rooms," Wolff wrote in the book. "In the first days, he ordered two television screens in addition to the one already there, and a lock on the door, precipitating a brief standoff with the Secret Service, who insisted they have access to the room."

According to Wolff, Trump's phobia led to "new rules" in the White House, such as cautioning the cleaning staff against ever touching his toothbrush and other personal items. He was so paranoid, Wolff claimed, the president even preferred to strip his own mattress of bedding and dictated when the bedding would be washed.

Wolff also linked the president's deep fear of being poisoned to his apparent adoration for fast food, especially McDonald's. It’s “one reason why he liked to eat at McDonald’s—nobody knew he was coming and the food was safely premade,” Wolff wrote.

It remains unclear if Trump believed a specific group or person was out to harm him.
