The joint appearance — their first of the campaign — was viewed by many as an audition for Clinton’s running mate, a choice that would create a historic all-female ticket.
One of the traditional tasks for a vice presidential candidate is to attack the other party’s nominee, and on that count, Warren certainly didn’t disappoint a crowd packed into a cavernous former passenger rail station here that now functions as a museum.
Warren called Trump “a small, insecure money grubber” and “a thin-skinned bully who is driven by greed and hate.” She said he was only interested in making America “great again” for “rich guys, just like Donald Trump.”
And Warren contrasted Clinton’s demeanor with that of Trump, saying the former secretary of state “doesn’t turn to Twitter to call her opponents fat pigs or dummies.”
Once Clinton took the microphone, she praised Warren as a politician “who tells it like it is.”
“I do just love to see how she gets under Donald Trump’s skin,” Clinton said, referring in part to Warren's recent battles with Trump over Twitter. “She exposes him for what he is: temperamentally unfit and totally unqualified.”
Clinton offered several of her own Trump broadsides, calling him “a man who plays coy with white supremacists and mocks people with disabilities.”
Clinton also used the event to highlight her policy agenda, emphasizing several issues that Warren has championed during her Senate career and echoing some of her rhetoric.
“I got into this race because I wanted to even the odds for people who have the odds stacked against them,” Clinton said.
Clinton also praised Warren’s work to protect consumers and to step up regulation of Wall Street, pledging that she would “strengthen the tough rules to rein in Wall Street.”
Hillary Clinton on the campaign trail
The joint appearance follows Warren’s endorsement of Clinton this month. The two also met for about an hour earlier this month at Clinton’s home in Washington, bolstering the VP speculation, as did a recent visit by Warren to Clinton’s headquarters in Brooklyn, where she told staffers: “Don’t screw this up.”
Warren is among the potential running mates who are being vetted by the Clinton campaign. Others include Housing and Urban Development Secretary Julián Castro and Sen. Timothy M. Kaine of Virginia.
Among other attributes, Warren seems the most likely of the potential Clinton running mates to excite supporters of Sen. Bernie Sanders (I-Vt.), Clinton’s vanquished primary rival.
Clinton was set to speak later Monday to the annual meeting of Rainbow PUSH Coalition, the civil rights organization founded the by Rev. Jesse Jackson.
The Chicago speech is Clinton's first civil rights-themed address since securing the Democratic nomination with a strategy geared to turning out black and Hispanic voters. Clinton is seeking to keep black voters engaged as the election contest with Trump focuses more heavily on Trump's business practices, policies on immigration and fitness to be commander in chief.
Clinton is also traveling to Denver and Los Angeles this week for a mix of campaign stops and fundraising.
Ohio and Colorado are among eight swing states where Clinton is concentrating time and advertising resources and where she is building large organizing operations.
Monday's visit was Clinton's third trip to Ohio in as many weeks.
