Vice President Kamala Harris said extremists want to “replace history with lies” as she traveled to Florida on Friday to assail Republican efforts to overhaul educational standards, plunging into a battle over schooling that has rippled through classrooms around the country.

“They dare to push propaganda to our children,” she said in Jacksonville. “This is the United States of America. We’re not supposed to do that.”

Her trip came two days after the Florida Board of Education approved a revised Black history curriculum to satisfy legislation signed by Gov. Ron DeSantis, a Republican presidential candidate who has accused public schools of liberal indoctrination. The new standards include instruction that enslaved people benefited from skills that they learned.

Harris, the first Black person to serve as vice president, spoke from the Ritz Theater and Museum, located in a historically African American neighborhood of Jacksonville.

She described “true patriotism” as “fighting for a nation that will be better for each generation to come,” and she said schools would better prepare students for the world if they don’t gloss over historical crimes.
