FBI Director Kash Patel says he has turned over documents detailing "alarming allegations" of interference by the Chinese Communist Party in the 2020 election to Senate Judiciary Committee Chair Chuck Grassley, R-Iowa.

"The FBI has located documents which detail alarming allegations related to the 2020 U.S. election, including allegations of interference by the CCP," Patel posted on X Monday. "I have immediately declassified the material and turned the documents over to Chairman Grassley for further review."

He linked his post to an article from Just the News, which reported Monday that the intelligence report raises concerns that the Chinese allegedly mass-produced fake U.S. driver's licenses to further a scheme to use fraudulent mail-in ballots for then-Democrat nominee Joe Biden.

The intelligence reports, dating back to August 2020, reportedly were not investigated but instead recalled from intelligence agencies.

Then-FBI Director Christopher Wray testified that there were no known foreign interference plots before the 2020 election, in which Biden defeated incumbent President Donald Trump.

Grassley has raised concerns that the intelligence reports were dismissed rather than being fully vetted.

"Thanks to the oversight work and partnership of Chairman Grassley, the FBI continues to provide unprecedented transparency at the people's Bureau," Patel told the outlet in a statement. "To that end, we have located documents Chairman Grassley requested, which detail alarming allegations related to the 2020 U.S. election."

He added that the allegations about the plan to facilitate fake mail-in ballots were "substantiated" but were "abruptly recalled and never disclosed to the public."

Unnamed sources who said they saw the documents told Just the News that the FBI has a new confidential source who had provided information back in 2020 that the Chinese government had been making and exporting fake U.S. driver's licenses.

The scheme, the source said, was to allow Chinese residents in the United States to create identities and vote with fake mail-in ballots to benefit Biden.

Although the report was recalled, U.S. Customs and Border Protection had intercepted approximately 20,000 fake licenses when the intelligence report was made, the sources commented.

Meanwhile, reports from 2020 indicated that CBP officials seized 19,888 counterfeit driver's licenses at the Chicago airport through the end of June of that year.

Fox News 5 in New York had reported that most of the shipments had come from Hong Kong and mainland China, with other shipments coming from South Korea and the United Kingdom.

The CBP at the time said that most of the fake IDs were for college-age students, and that many had the same photos but different names.

Meanwhile, just last month, customs agents intercepted shipments at Chicago's O'Hare Airport that included thousands of fake driver's licenses and counterfeit designer watches, reports CBS News.

In the 485 shipments from Hong Kong and China, 145 contained 516 counterfeit Rolex and other watches, and 340 other shipments contained 4,345 fake U.S. driver's licenses.
