The U.S. Department of Education launched an investigation into the transparency of foreign funding received by Harvard and Yale universities.

Officials suspect that these institutions failed to report billions of dollars worth of contributions originating from abroad, some even from countries opposed to the United States, according to The Wall Street Journal.

The universities are reportedly becoming “multibillion-dollar, multinational enterprises using opaque foundations, foreign campuses, and other sophisticated legal structures to generate revenue,” according to a description by the Department of Education.

An estimated $6.5 billion in unreported money has been received by universities across the country, contributed by nations such as Saudi Arabia and Qatar and by systems such as that of the Chinese regime.

Of particular concern is the involvement of entities such as the Yenching Academy at Beijing University, the National University of Singapore, and giant telecommunications companies under the influence of the Chinese communist regime, Fox News reported.

Agents of the Chinese regime have been accused over and over of espionage in the most important areas of the nation, and of stealing industrial secrets, and of stealing from other institutions for their own benefit.

The FBI believes that spying by the Chinese communist regime is the greatest threat to the United States, as espionage cases are investigated and arrests have increased at an unprecedented rate.

FBI Director Christopher Wray reported on the nearly 1,000 investigations conducted by his 56 offices involving almost all industrial activities, according to the Washington-based Center for Strategic and International Studies.

Secretary of State Mike Pompeo also spoke at the Feb. 8 National Governors Association (NGA) winter meeting about the influence of the Chinese regime on the country.

“And while these might seem like local matters to some, the cumulative effect is of enormous national importance and international significance,” Pompeo said.

He also said the “so-called Thousand Talents Plan is a plan to recruit scientists and professors to transfer the know-how we have here to China in exchange for enormous paydays.”

And he addressed the issue of the Confucian Institutes, which apparently provide Mandarin language courses but serve as a tool to promote a positive image of the Chinese communist regime.

Additionally, Pompeo urged the governors to “protect our security, our economy; indeed, all that we hold dear, all of those freedoms.”
