Many people suffer from what is known at Trump Derangement Syndrome, which just seems to be a condition of them not being able to regulate their own emotions and function as normal human beings in life. Joe Biden happens to be one of them.

According to the forthcoming book “The Fight of His Life: Inside Joe Biden’s White House” by Chris Whipple, Joe Biden gets upset and angry when he comes across reminders of former President Trump within the White House.

This reportedly includes a large screen television and a $50,000 golf simulator that Trump personally paid to have installed, which allows him to play virtual golf on almost any golf course in the world. “‘What a f***ing a**hole’ Biden said, showing the contraption to a guest,” Biden said as he showed the simulator to a guest at the White House.

Biden is said to have a strong hatred for Trump and even refuses to use items that the he used. The book also claims that Biden was paranoid that Secret Service personnel were loyal to Trump.

In addition, the book states that Biden became enraged upon seeing scenes of illegal immigrants flooding the southern border of the United States. According to a copy obtained by Fox News, the book says, “Aides had rarely seen him so angry. From all over the West Wing, you could hear the president cursing, dropping f-bombs (he’d always apologize when women were present).” A senior Biden official reportedly told the author that this anger stemmed from a “lack of solutions” to the crisis. The book also notes that Biden began using profanity more frequently as other crises arose.

Earlier this month, it was revealed that Biden allegedly called Kamala Harris a “work in progress” in the book. Harris has reportedly struggled in her first two years in office. According to POLITICO, Biden became annoyed upon learning that Harris’ husband was complaining about the policy portfolio assigned to her as vice president. Another senior administration official reportedly agreed, stating that Harris’ inner circle “didn’t serve her well in the presidential campaign, and they are ill-serving her now.”
