Rep. Elise Stefanik of New York, the House Republican Conference chair, is pushing back on the criticism of her Facebook ads that featured rhetoric echoing the racist “replacement theory.” The conspiracy theory claims liberal politicians are trying to replace White people with non-White people to transform the political landscape. There is renewed scrutiny on Stefanik’s ads from last fall after a suspect who espoused the "replacement theory" killed and targeted Black people in a mass shooting in Buffalo, New York, over the weekend. #CNN #News
