Even though Hillary Clinton is officially the presumptive Democratic nominee, her chief rival, Vermont Sen. Bernie Sanders, has repeatedly suggested he will stay in the race until the convention.

One day after meeting with President Obama, the self-described democratic socialist will host a massive rally Thursday afternoon in the RFK Stadium parking lot in D.C. The doors open for the event at 4 p.m. ET, and Sanders is expected to speak at 7 p.m.

“The Democratic Party presidential candidate will hold a rally in Southeast D.C.,” a statement from the Sanders campaign announced. “Sanders will discuss a wide range of issues, including getting big money out of politics, his plan to make public colleges and universities tuition-free, combating climate change and ensuring universal health care.”

Some have speculated that Sanders could use the speech to officially concede the race and throw his backing behind Clinton, in the fight against Trump, while others believe he will stick it out past next week’s D.C. primary vote.

The speech will likely air across the cable news networks, but those without a television can live-stream the full speech below, via YouTube.
