The disclosure was made in a motion seeking to dismiss seditious conspiracy and obstruction charges against 10 Oath Keepers defendants in one of the most prominent Jan. 6 criminal cases.

David W. Fischer, attorney for Thomas E. Caldwell of Berryville, Virginia, filed a 41-page motion to dismiss four counts on behalf of all Oath Keepers case defendants before U.S. District Judge Amit P. Mehta in Washington, D.C.

Caldwell is charged in the indictment, but is not a member of the Oath Keepers, he told The Epoch Times in March.

"At least 20 FBI and ATF assets were embedded around the Capitol on J6," read a footnote on Page 6 of the motion. No other details were provided in the document.

The footnote said defense attorneys "combed through a mountain of discovery," including FBI form 302 summaries of interviews conducted by FBI agents.

In addition to the information about law-enforcement assets on the ground at the Capitol, the footnote says, the Oath Keepers "were being monitored and recorded prior to J6."

Poring over evidence turned over in discovery by prosecutors in two major Oath Keepers cases has "not found one iota of proof" that defendants "had any plan, intention, design, or scheme to specifically enter the Capitol Building on J6," the motion said.

Fischer told The Epoch Times he could not comment on the motion or provide more details on the footnote.

Since the first arrests of Jan. 6 defendants in early 2021, there has been extensive speculation and questions from attorneys, defendants, case observers, and members of Congress about the role law enforcement played that day.
