Kevin Clinesmith plans to accept a charge of changing an email to another official in 2017 who said Page was not a previous government source when he had been one.
Clinesmith had also been critical of President Donald Trump when he worked for the FBI.
Friday’s indictment represents the first public production from the long-awaited Durham investigation and is likely to provide political fodder for Trump amid a storm of negative headlines about his management of the coronavirus pandemic.
“Kevin expresses deep regret over the email change,” Clinesmith’s lawyer, Justin Shur, said in a statement Friday. “It was never his intention to deceive the court or his colleagues as he believed the information he transmitted was correct. But Kevin realizes what he did was wrong and accepts responsibility.”
