Joe Biden’s reelection campaign limped into the U.S. Independence Day holiday, exhausted by a week of the incumbent clawing to maintain his hold on his party’s nomination.

The president is scheduled to host a Fourth of July barbecue with military families Thursday afternoon and to later deliver remarks and watch fireworks from the White House grounds. It’s been exactly seven days since his disastrous debate performance against Donald Trump intensified questions about his fitness for office, and triggered calls from within his own party for him to suspend his reelection bid.
