DES MOINES, Iowa — Joe Biden Wednesday bragged about time he spent in the “hood,” a place where he said he found “women of color” he helped train to do computer coding.

Speaking at a rally, the former vice president elaborated on how U.S. workers need to receive better education to prepare themselves for a changing economy, and used a visit to Detroit, Mich., to describe how businesses went to local organizations that help train minorities various coding and technical abilities.
