The event starts at 10:30 a.m. at the Cincinnati Museum Center at Union Terminal. Doors open at 8:30 a.m.
With Sen. Bernie Sanders fading from the spotlight, Warren is stepping up to reclaim her role as leader of the progressive wing of the Democratic Party. She's mobilizing her forces behind Clinton, lending her presidential bid a powerful boost of liberal credibility.
The two women have formed a tight electoral alliance, one that could grow even closer should Warren be selected as Clinton's running mate.
She's currently being vetted by lawyers charged with running the vice presidential process. They've already asked Warren to complete a questionnaire and for documents.
For Clinton, the visit offers an opportunity to win back some of the liberal and younger voters she lost to Sanders in the primary season.
“At a public event in Cincinnati, Clinton and Warren will discuss their shared commitment to building an America that is stronger together and an economy that works for everyone, not just those at the top,” read a prepared statement from Clinton’s camp.
