President Joe Biden warned in a primetime speech Thursday that Donald Trump and his supporters pose an existential threat to democracy in the United States. Biden spoke in Philadelphia in front of Independence Hall, where the Declaration of Independence and U.S. Constitution were debated and signed.

President Joe Biden: “But as I stand here tonight, equality and democracy are under assault. … Donald Trump and the MAGA Republicans represent an extremism that threatens the very foundations of our republic.”

Biden’s remarks came less than 10 weeks before midterm elections, with control of both the House and Senate at stake. After headlines, we’ll air extended clips of Biden’s speech.
