Trump was speaking at a General Motors plant in Milford, Michigan, praising American automakers, when he lapsed into an anecdote about his father, Fred Trump, who died in 1999, that left onlookers scratching their heads. “I had a wonderful father, right, and he was a hard worker who was in the real estate business ... Fred Trump was born in 1905 and died in 1999, and as critics pointed out, the Wright Brothers famously made the first powered flight two years before he was born. Others piled on with more detail, noting the first commercial flight was a 17-mile hop from Tampa to St Petersburg in 1914 — when Fred Trump was nine.” This is far from the first time speculation has been raised about Trump’s mental health.
