Hillary Clinton's latest line of attack on Donald Trump calls him a "con man." | Getty Clinton camp leverages Rubio 'con man' hit on Trump

Hillary Clinton's campaign on Wednesday looked to take up the mantle of Mitt Romney and Marco Rubio, who once denounced Donald Trump as a "con man," kicking off a series of tweets hitting the presumptive GOP nominee for his business practices with Trump University by employing his fellow Republicans' words against him.

"Trump U is devastating because it's metaphor for his whole campaign: promising hardworking Americans way to get ahead, but all based on lies," Clinton press secretary Brian Fallon tweeted, adding, "Rubio's strongest moment was when he called Trump a con man based in part on Trump U. Rubio wasnt around long enough to make case. We will"


Clinton's own account retweeted the first message from Fallon, all while relaying reports from The New York Times and The Washington Post that chronicled findings from documents that were formally unsealed on Tuesday. Those documents featured employee guides that, the Times reported, "pushed employees to exploit the emotions of potential customers." (Trump has steadfastly denied that Trump University, which is now defunct, misled students.)

"Urgency is proportional to pain. Problems are like health. The more a problem hurts now, the more the need for a solution now. And the more it hurts, the more they'll be prepared to pay for a speedy solution. It's got to hurt enough!" reads one of the bulleted items in a playbook for Trump University salespeople.

In the Post report shared by Clinton, the story cited "documents from employees who described Trump University as a scam."

"Based upon my personal experience and employment, I believe that Trump University was a fraudulent scheme, and that it preyed upon the elderly and uneducated to separate them from their money," a former employee said in one of the documents from 2012.

Rubio, who has said he regretted the more personal aspects of his Trump attacks and has even offered to speak on his behalf at the Republican National Convention, assailed his primary opponent in the final weeks of his campaign over his past business dealings, including the for-profit institution currently facing multiple lawsuits.

Fallon later retweeted a three-month old Rubio tweet accusing Trump of "[duping] everyday Americans," adding, "What he said -->"

Clinton then retweeted an 89-day old tweet from Mitt Romney calling Trump a "phony" and a "fraud."

"Trump's for-profit university deceived & exploited students to take their money. And he has the gall to call the media 'sleazy,'" Clinton tweeted, alluding to his calling a reporter a "sleaze" on Tuesday during a news conference.
