Donald Trump and the MAGA Republicans represent an extremism that threatens the very foundations of our republic. Now, I want to be very clear - (applause) - very clear up front: Not every Republican, not even the majority of Republicans, are MAGA Republicans. Not every Republican embraces their extreme ideology. I know because I've been able to work with these mainstream Republicans. But there is no question that the Republican Party today is dominated, driven, and intimidated by Donald Trump and the MAGA Republicans, and that is a threat to this country.
