Former Vice President Joe Biden said Tuesday that he'll announce his running mate "the first week in August."

The big picture: Last week, Biden seemed to back away from his timeline of early August, but he recommitted to it Tuesday at a speech in Delaware announcing his plans for fighting systemic racism.

  • "I promise, I’ll let you know when I do," Biden joked with reporters about his decision.
  • Biden played coy on whether he would interview finalists in person and if he'd wear a mask: "Well, we'll see," he said.
  • He said he hadn't been tested for COVID-19.

Where it stands: Biden has pledged to name a woman as his running mate, and last week told MSNBC that among the finalists are "four Black women."

  • His team has been vetting Sen. Kamala Harris, former national security adviser Susan Rice, and Reps. Val Demings and Karen Bass as potential running mates.
  • He told MSNBC last week that he would meet the finalists in person, promising “personal discussions with each of the candidates who are left and make a decision.”

What we're hearing about Joe Biden picking Sen. Kamala Harris as his running mate from the text chain of the Axios political team.

White House editor Margaret Talev: So far, Harris has been the hardest for Trump to brand. The initial Trump campaign response is to brand her as a sellout willing to look past her earlier concerns about Biden.

Biden running mate news triggers "best grassroots fundraising day ever"

More than $10.8 million was donated in four hours after Sen. Kamala Harris was announced as presumptive Democratic presidential nominee Joe Biden's running mate Tuesday, the Democrats' main donation-processing platform ActBlue said, per the New York Times.

Why it matters: Biden is lagging behind in fundraising to President Trump, whose campaign and the Republican National Committee out-raised that of the Democrats' last month. But Biden's announcement triggered his campaign's "best fund-raising hour," his deputy digital director, Clarke Humphrey tweeted, adding it was the campaign's "best grassroots fundraising day ever." ActBlue took $2.3 million in donations during the same hours of 4pm to 8pm Monday, "suggesting a bump as large as $8.5 million" for Biden, the Times notes.
