Danchenko will appear in the Eastern District of Virginia later Thursday. The charges are still under seal.
Attorneys for Danchenko did not immediately respond to a request for comment.

In September, Durham issued a new set of subpoenas, including to a law firm with close ties to Hillary Clinton’s 2016 campaign, an indication that he could be trying to build a broader criminal case, according to people briefed on the matter.

The most recent grand jury subpoenas for documents came after Durham charged Clinton campaign lawyer Michael Sussmann with lying to the FBI in a September 2016 meeting.
