Fox News host Howard Kurtz called out Republican National Committee (RNC) co-chair Lara Trump after she insisted that Vice President Kamala Harris lost to President-elect Donald Trump by "insulting people." "If you're running for president of the United States, you better lay out a great plan for the American people and tell them how you're going to make their life better, not just continually attack the opposition," Trump told Kurtz in a Sunday interview on Fox News. "And I think whenever they got to a level of just insulting people and trying to harass people into voting for them, that's kind of how when you lose the American public, when people say, you know what, I don't want to be insulted into voting for someone," the RNC co-chair added. "But couldn't Democrats say the same?" Kurtz pushed back.
