UPDATED: 11:14 a.m. EDT — Massachusetts Sen. Elizabeth Warren and Hillary Clinton showered each other with praise while lambasting Donald Trump during the duo's joint appearance Monday at a rally for the presumptive Democratic presidential candidate in Cincinnati, Ohio.

Warren needed just three words early in her speech to sum up why she was there: "I'm with her," Warren proclaimed, while pointing to her right at Clinton to thunderous applause. But she wasn't done with her address by any means, going on to explain why she was appearing alongside the presumptive Democratic presidential candidate for the first time since lending her endorsement earlier this month.

Clinton has a "good heart," and "that's what America needs," Warren said matter of factly before launching into a stern tongue-lashing aimed at Trump, who she called a "small, insecure money-grubber."

Warren, who compared her humble beginnings to those of Clinton, listed many of the differences between Clinton and Trump, whom she labeled as a sexist, a racist and a hater. Those attributes "have no place in our country," she said before introducing a beaming Clinton while they waved to the crowd in concert, arm-in-arm.

Clinton, in turn, returned Warren's warm remarks, calling the Massachusetts senator "my friend and a great leader" who "is considered so terrific, so formidable — because she tells it like it is." Oh, and there was one other aspect of Warren that Clinton said she appreciated so much: "I do just love to see how she gets under Donald Trump's thin skin."

When the smoke cleared from all the Trump bashing, Clinton focused more on policy while talking about many of the financial issues that her Democratic primary opponent Vermont Sen. Bernie Sanders championed for much of the past year: trash talking Wall Street, blasting tax breaks for wealthy and vowing to eliminate student debt.

"We must have an economy that works for everybody again, not just for those at the top," she said before promising: "I am going to raise taxes on corporations and the wealthy! ... We've got the greatest economy and country in the world. It's time to start acting like it."

She also hinted that Warren may have a place in a future Clinton presidential administration by starting a sentence with, "As soon as we start to work, Elizabeth..."

Original story:

Democrats on Monday morning finally get to see a pairing many on the left have been talking about for months. Massachusetts Sen. Elizabeth Warren is scheduled to join presumptive Democratic presidential nominee Hillary Clinton onstage at a rally in Cincinnati.

The event is scheduled for 10:30 a.m EDT at the Cincinnati Museum Center at Union Terminal. To watch a live stream of the event, click here or watch the embedded video at the bottom of the page.

Warren, an admired leader among progressives, is reportedly on Clinton's short list of possible vice presidential candidates. The senator has endorsed the former secretary of state and has proved especially adept at attacking presumptive Republican presidential nominee Donald Trump.

"I’m ready to get into this fight to make Hillary Clinton the president of the United States and be sure that Donald Trump gets nowhere near the White House," Warren said this month on MSNBC’s "Rachel Maddow Show."

A political alliance with Warren is especially important for Clinton, who is attempting to win back voters from Vermont Sen. Bernie Sanders, her Democratic competitor. Warren could be a draw for the young, liberal demographic that was drawn to Sanders, who has said he would for vote for Clinton but to date has stopped short of a complete endorsement.

"It sends a clear signal to progressive voters that it's time for them to put the past in the past and elect Clinton," Geoff Garin, a pollster at Priorities USA, a super PAC backing Clinton's bid, told ABC News. "Sen. Warren carries an enormous amount of credibility with exactly the same kind of people who were avidly supportive of Sanders in the primary."

The relationship between the two women has not always been great. Warren leans further left than Clinton, and the senator has been a vocal critic of Wall Street, which has been a fertile ground for donors to the candidate.

But recently the relationship between the two has seemingly grown friendlier. Warren stopped in this month to visit with staff members at Clinton's Brooklyn, New York, campaign headquarters.

"Don't screw this up," Warren told the campaign, according to CNN, which cited attendees.
