President Donald Trump discussed his older brother’s struggles with alcoholism on Thursday during his address declaring the opioid epidemic in the United States to be a national health emergency, saying he learned from his brother’s “very tough” life.

Fred Trump, Jr., died in 1981 as an alcoholic at the age of 43, and his younger brother has previously said watching Fred’s suffering caused him to avoid alcohol and cigarettes.

“I learned myself. I had a brother, Fred. Great guy. Best-looking guy. Best personality. Much better than mine,” Trump said in remarks at the White House. “But he had a problem. He had a problem with alcohol. And he would tell me, ‘don’t drink. Don’t drink.'”

Trump, who was eight years his junior, said he listened to his brother’s admonitions, and to this day has never had a drink.
