President Joe Biden will mark the third anniversary of the Jan. 6 attacks on the U.S Capitol with a political speech the day before to make the case that Republican Donald Trump poses an existential threat to democracy, Biden’s re-election campaign said on Wednesday.

Biden’s campaign said he will speak near Valley Forge, Pennsylvania, where George Washington established headquarters during the Revolutionary War. The speech site, Montgomery County Community College, is about 15 miles away.

Biden will follow the Friday visit with a campaign stop on Monday at Mother Emanuel AME Church in Charleston, South Carolina, where a white supremacist in 2015 killed nine parishioners at the historic Black church.

Biden had planned to deliver his Pennsylvania remarks on Saturday, the actual anniversary of the Jan. 6, 2021, assault on the U.S. Capitol by Trump supporters, but moved it to Friday to avoid a forecast winter storm.
