Bernie Sanders’ last stand may well have been in a parking lot in the nation’s capital, surrounded by his campaign’s faithful.

“Here we are in June and still standing,” the Vermont senator told supporters at a rally of more than 3,000 on Thursday night.

The event might well be the final one of his presidential bid with the District of Columbia set to conclude the primary season on Tuesday.

Sanders addressed the excited crowd gathered in the parking lot of Robert F. Kennedy Stadium. Earlier in the day, he met with President Barack Obama and Democratic leaders of the Senate, signaling the beginning of the end of his campaign.

He ended his day on a picture-perfect spring night, surrounded by supporters who said they showed up to prove to Sanders that they still had his back after he officially fell short in primary and caucus balloting to Hillary Clinton, now the presumptive Democratic nominee.
