Wu "was terminated because he did not cooperate with an internal examination of the University's admission affairs," the spokeswoman said.
The student, her parents, and Wu were not charged in the scandal.
Investigators were early aware of the information, but did not have enough evidence to file a bill in March, the source added. The investigators are examining Morgan Stanley and the parents to find out what they know.
Stanford University made a statement after the report.
"It is important to clarify that Stanford has not received $ 6.5 million from Singer or from students. Family works with Singer," it said. "Stanford did not know the family-reported payment of $ 6.5 million to Singer until today's news."
Who is behind the scam?
Singer, the supposed mastermind of the system, worked with dozens of wealthy parents to unjustly take their children to top universities.
He was the owner of the college counseling and preparation business, known as "The Key," and the CEO of the Key Worldwide Foundation, the charitable organization associated with it.
Through these organizations, he allegedly alleviated both frauds in standardized tests such as the SAT and ACT and bribery of college coaches and administrators to mistakenly label children as recruited athletes, even if they did not practice this sport.
Fifty people – including Hollywood stars, top CEOs, college coaches, and standardized test administrators – reportedly participated in the program to cheat tests and allow students to run as leading athletes, regardless of their abilities. At least eight universities are named in an indictment and a federal criminal complaint.
Singer received about $ 25 million from parents as part of the project, said Andrew Lelling, the US attorney for Massachusetts. Part of this money was then used to pay for trial administrators or trainers as part of the program.

Actress Felicity Huffman was among more than a dozen parents who pleaded guilty to fraud last month. In return for the guilty plea, the prosecutors declared that they would recommend imprisonment at the "lower end" of the sentence and make no further charges against them.
