Donald Trump delivered a rambling speech in Pittsburgh, Pennsylvania, where he made several improbable claims and appeared to forget names.Trump falsely asserted that his late uncle, Dr. John Trump, taught Theodore Kaczynski, the Unabomber, at MIT, despite Kaczynski never attending the institution.He also claimed to have discussedKaczynski with his uncle, which is highly unlikely as his uncle died in 1985, years before Kaczynski was identified as the Unabomber
