Dennis Prager

1948 – 20??

Dennis Mark Prager is an American conservative radio host and writer who in 2009 co-founded PragerU, an online video operation that produces five-minute commentaries advocating conservative political, economic, and cultural positions while branding itself as an educational institution. PragerU is not an accredited university and its videos have repeatedly been fact-checked as misleading on topics including climate change, racial slavery in the United States, and pandemic public-health measures. Several U.S. states have nonetheless approved PragerU content for use in K–12 classrooms.
