President Donald Trump likes to boast about the brilliance of his late uncle John Trump, who spent decades as a professor of electrical engineering at the renowned Massachusetts Institute of Technology (MIT). And when speaking about all manner of subjects, the president likes to make up stories filled with dramatic but fictional details. On Tuesday, Trump conjured an especially odd imaginary tale – that linked his uncle with the late terrorist Theodore “Ted” Kaczynski, better known as the Unabomber. #CNN #news
