President Joe Biden is spending much of his time this week speaking directly to Black voters, a constituency that carried him to the White House in 2020 and whose voters are now threatening to withhold their support as Biden’s final presidential campaign unfolds.

Biden’s most high-profile event this week is still to come. On Sunday, he will deliver a commencement speech at Morehouse College, a prestigious, historically Black institution. But he has spent the days leading up to it running down a list of achievements and otherwise making his message clear: “My name’s Joe Biden, and I’m a lifetime member of the NAACP,” he said during a speech Friday.

He was speaking to a crowd at the National Museum of African American History and Culture celebrating the 70th anniversary of Brown v. Board of Education, a landmark civil rights ruling that outlawed racially segregated schools.

Not even the venue choice seemed like a complete coincidence: As a senator, Biden was one of the original co-sponsors of legislation establishing the museum, and he attended its opening as vice president in 2016.
