WASHINGTON — The Clinton Foundation has raked in more than $1 million in just three years from colleges and universities willing to pay big bucks to host its annual networking event.

The University of Miami — which is headed by former Bill Clinton Secretary of Health and Human Services Donna Shalala — shelled out at least $250,000 in March for the multi-day program called the Clinton Global Initiative University, foundation records show.

The Florida school refused to specify the total amount it spent to host the program, which featured headliners Bill and Chelsea Clinton.

“There was a payment for a speaking fee that was underwritten by a private donor,” Margo Winick, the school’s assistant vice president of media relations, told The Post. “We bring speakers of all walks of life to campus all the time.”

Shalala is set to take over the Clinton Foundation on Monday.

Arizona State University also paid a whopping $500,000 for the event last year, records show.

“If I would have known that was the situation . . . that they were being paid $500,000, I would have spoken up at the time that I thought it was outrageous,” Sen. John McCain (R-Ariz.) told The Arizona Republic last week.

Not every school pays, and some even receive money from the foundation.

When the University of Texas, Tulane and George Washington University hosted the annual event, there was no fee. Texas’ student government actually billed the foundation for $28,000 worth of expenses and got reimbursed, the school told The Post.

It’s unclear how the fees get determined for the schmooze fests, which bring together CEOs, entrepreneurs, entertainers and students. Students from 875 schools and 145 countries have participated since the program’s inception in 2009, according to the foundation.

The first disclosed payment appears to involve the 2013 conference at Washington University in St. Louis, where records show that the school paid up to $250,000.

Schools are interested in hosting the event because it “helps advance their academic mission by bringing together leaders from business, government, philanthropy, technology, media, the arts and culture together on campus to work with students,” according to Clinton Foundation spokesman Craig Minassian.

The event has brought students together with CEOs such as the head of Boeing, former House Minority Leader Richard Gephardt and even TV host Jimmy Kimmel. The Clinton Global Initiative says it formed the initiative to launch the “next generation of leaders.”

A Clinton Foundation official insisted everything was kosher.

“CGI does not make a profit for these events, and all the funding goes toward logistics and production of the event itself,” a foundation official said.
