According to the Wall Street Journal, the Department of Education is continuing a review that American colleges did not disclose $6.5 billion in foreign funding, including monies from China and Saudi Arabia. 

In a letter to Harvard, the Department of Education asked the Ivy League institution to disclose all information regarding gifts and connections to China, Iran, Qatar, and Saudi Arabia. The Department of Education also asked Harvard to disclose any connections it may have to Huawei and ZTE, two Chinese telecommunications companies, and Kaspersky Labs, the Russian cybersecurity firm.

The Wall Street Journal previously reported that Huawei has been accessing mobile phone networks around the world through "back door" methods traditionally used by law enforcement.
