DOUGLAS, Arizona — In her most forthcoming comments to date on immigration, Vice President Kamala Harris vowed to increase security at the U.S.-Mexico border and prevent illegal border crossings, promising to go further than President Joe Biden’s recent successful actions to stem the flow.

The Democratic presidential nominee charmed the several hundred supporters on-site at Cochise College in southeastern Arizona with a major speech that provided the most significant indication of how she would handle immigration and border policy if elected in November.
