Voters in Indiana haven't backed a Democratic presidential candidate in nearly 16 years. But when Vice President Kamala Harris heads to the solidly Republican state on Wednesday, she'll speak to a constituency she hopes will turn out for her in massive numbers in November: women of color.

Just three days after launching her bid for the White House following President Joe Biden's departure from the race, Harris will address the biennial gathering of the historically Black sorority Zeta Phi Beta in Indianapolis.
