Donald Trump’s Wednesday morning speech about Hillary Clinton’s record is probably the most unnervingly effective one he has ever given. In a momentary display of discipline, he read from a teleprompter with virtually no ad-libbing, avoiding digs at Bill Clinton’s infidelity or conspiracy theories about Vince Foster’s suicide. Standing in a low-ceilinged conference room bedecked with square chandeliers in the Trump SoHo, a lawsuit-plagued hotel and condo development, Trump spoke for 40 minutes without saying anything overtly sexist. Instead, he aimed straight at Clinton’s most-serious weaknesses, describing her as a venal tool of the establishment. “Hillary Clinton gave China millions of our best jobs and effectively let China completely rebuild itself,” he said. “In return, Hillary Clinton got rich!” He added, “She gets rich making you poor,” and called her possibly “the most corrupt person ever to seek the presidency.”

The point is not that this is true; as political analyst David Gergen said on CNN, the speech was slanderous. But the lies in the speech, many taken from Peter Schweizer’s book Clinton Cash, were not obviously self-refuting. At one point, Trump said, citing Schweizer, “Hillary Clinton’s State Department approved the transfer of 20 percent of America’s uranium holdings to Russia, while nine investors in the deal funneled $145 million to the Clinton Foundation.” This has been debunked many times over, including by FactCheck.org.
