Presumptive Democratic presidential nominee Joe Biden is accelerating his outreach to black voters with tailored grassroots events and advertising dedicated to engaging this crucial bloc on Friday.

One day before President Trump was to rally in person with thousands of supporters in Tulsa, Oklahoma, the Biden campaign was holding virtual gatherings with black voters across 10 battleground states in which their participation is critical: Colorado, Florida, Michigan, North Carolina, New Hampshire, Ohio, Pennsylvania, Virginia, and Wisconsin. The former vice president also unveiled a well-funded advertising campaign in black media outlets that includes a week of full-page ads in the Oklahoma Eagle, a black-owned newspaper in Tulsa.
