Joe Biden has winnowed down his vice presidential shortlist to a selection of names that includes four black women.

“I am not committed to naming any but the people I’ve named, and among them, there are four black women,” Biden told MSNBC Monday. “It is important that my administration, I promise you, will look like America.”

The presumptive 2020 Democratic presidential nominee and two-term vice president detailed extensively for the first time the process he’s undertaking before he unveils his pick before the national convention, slated for Aug. 17-20 in Milwaukee, Wisconsin. That process incorporates two-hour vetting reports, four of which he’d already received.

“When I get all the vetting done of all the candidates, then I’m going to narrow the list, and then I’m going to have personal discussions with each of the candidates who are left and make a decision,” he said.
