President Trump does not drink alcohol. Many know that is because his brother Fred died from alcoholism-related conditions.

Now, the president is opening up about the effect that has had on his wife.

According to Fox News:

President Trump reflected on his relationship with his brother Fred Trump Jr. — who died in 1981 as a result of alcoholism — and the lasting effect Fred’s drinking had on him, saying in an interview he regrets the “pressure” put on his sibling.

…

The president also lamented how he treated his older brother when it came to the family business. While Donald Trump was eager to stand beside their father, Fred Jr. dreamed of being an airline pilot. The president fears the pressure his brother faced may have led to his drinking problem.

“I do regret having put pressure on him,” Trump said, recognizing that taking over their father’s business “was just something he was never going to want.”

Looking back, the president said, “I think the mistake that we made was we assumed that everybody would like it. That would be the biggest mistake. . . . There was sort of a double pressure put on him.”

President Trump also stated that his brother’s addiction is probably the main reason why he expends so much, time, energy, and resources on combatting the opioid crisis.
