WASHINGTON — The campaign of the presumptive Republican presidential nominee Donald Trump took sharp aim at Sen. Elizabeth Warren, D-Mass., on Monday, accusing her of hypocrisy as she campaigned alongside presumptive Democratic nominee Hillary Clinton.

The Trump campaign claimed that while Warren has criticized the New York real estate businessman for taking contributions from Wall Street, Clinton has accepted more than $41 million from "Wall Street interests."

"Warren's campaigning for Clinton stands in stark contrast to the liberal ideas she once practiced," the Trump campaign said in a statement entitled "Sellout Warren." "This sad attempt at pandering to the [Sen. Bernie] Sanders wing is another example of a typical political calculation by D.C. insiders."

Trump's attacks are a preview of what he is likely to claim if Warren becomes Clinton's running mate. Warren has become one of Trump's more effective critics, hitting him hard on Twitter and in speeches. Her criticism appears to have rankled Trump, who repeatedly goes after Warren instead of Clinton herself.

Clinton and Warren campaigned together for the first time Monday in Ohio, with Warren accusing Trump of believing that "poor, sad little Wall Street bankers need to be free to defraud anyone they want."

"Hillary Clinton believes that we need strong rules to prevent another financial crisis," Warren said.

For her part, Clinton vowed to "defend and strengthen the tough rules to rein in Wall Street that were put in place after the crash."

"When corporations pay fines for breaking the law, those fines should cut into executives' bonuses," she said. "And if laws are violated, individuals, not just corporations, should be held accountable."

Clinton also said she would reject any efforts to weaken protections for consumers and credited Warren with creating the Consumer Financial Protection Bureau.

"It's only been around a few years, but it has already returned over $10.8 billion to 25 million Americans who have been hurt by illegal financial practices," Clinton said. "Now, that is what standing up and fighting to right economic wrongs looks like."
