Sen. Elizabeth Warren (D-Mass.) will join Hillary Clinton on the campaign trail Monday in Cincinnati, the presumptive Democratic nominee's campaign announced Wednesday.

"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," the campaign said in its announcement.


Warren has been an outspoken surrogate for Clinton, and is reported to be on the former secretary of state's shortlist for vice presidential candidates. The liberal Massachusetts senator visited Clinton's campaign headquarters in Brooklyn last Friday, where she told staff, "Don't screw this up."

Republican National Committee spokesman Michael Short blasted Clinton and Warren in a statement, noting their stylistic and substantive differences on the financial industry.

“This event will complete one of the biggest sellouts in political history given that Hillary Clinton is everything Elizabeth Warren supposedly stands against," Short said. "Watching Elizabeth Warren defend Hillary Clinton’s refusal to turn over her Wall Street speech transcripts will be as priceless as the accounts of her attending fundraisers with the same hedge-fund managers she built a career demonizing.”
