During the rally, Trump also lashed out at potential rivals in the 2020 presidential election, including Oprah Winfrey and Senators Bernie Sanders and Elizabeth Warren. Trump also blasted NBC News political director Chuck Todd as a “sleepy-eyed son of a bitch.” And he mocked California Democratic Congressmember Maxine Waters, saying she has a “very low IQ.” Trump’s rally in Western Pennsylvania came ahead of Tuesday’s special election for an open congressional seat. Republican Rick Saccone is in a tight race with Democrat Conor Lamb for Pennsylvania’s 18th Congressional District, which Trump carried by 20 points during the 2016 election.
