President Donald Trump opened up about his older brother’s struggle with alcoholism during a Thursday speech in which he called the opioid epidemic a “public health emergency” and a “human tragedy.”

Trump’s brother, Fred Trump Jr., was eight years older than the president and died in 1981 at age 43. In a rare moment of vulnerability, Trump said he learned a great deal from watching how his brother, a former pilot, struggled with alcoholism for years.

“I had a brother Fred — great guy, best-looking guy, best personality, much better than mine,” Trump told the crowd gathered in the East Room of the White House. “But he had a problem, he had a problem with alcohol.”
