Federal authorities looking into the Jan. 6, 2021, insurrection are investigating former Justice Department official Jeffrey Clark for conspiracy, obstruction and making false statements, a recent filing by the D.C. Bar published on Wednesday showed, according to multiple news reports.

Federal investigators searched Clarks Virginia home in June . His lawyer said the authorities recovered electronic devices as part of a criminal probe into the three Jan. 6-related charges and that only one of the seized devices was returned to him earlier this month, CNN reported .

Clark, a former environmental lawyer in the DOJs Civil Division, is also facing ethics charges from the D.C. bar for his involvement in pushing former President Donald Trump s lies about the 2020 presidential election.

Clarks lawyers asked for a delay in the D.C. Bars proceedings, citing the other pending investigations into their client by the DOJ, the Jan. 6 House select committee and the Fulton County, Georgia, district attorney but the request was denied, according to a filing released Tuesday and reported by The Hill .

Clark has disputed the ethics charges.

At no time has President Trump complained about the legal, factual, and/or policy advice he received from respondent or voluntarily submitted a dispute of that nature to the D.C. Bar for investigation and adjudication, his lawyers wrote in a filing earlier this month, according to Bloomberg .

Hamilton P. Fox III, the disciplinary counsel for the D.C. bar, charged Clark with attempting to engage in conduct that would seriously interfere with the administration of justice.

In December 2020, Clark allegedly wrote a draft Proof of Concept letter falsely claiming the Justice Department had identified significant concerns that may have impacted the outcome of the election in multiple States, including the State of Georgia. Clark also laid out a plan to replace electors for Joe Biden with ones in favor of Trump in several states, which would have disrupted the certification of the now-presidents win.

Clark pressed acting Attorney General Jeffrey Rosen, and his deputy, Richard Donoghue, to send the letter, but they refused.

Trump had considered appointing Clark in Rosens place, but didnt go ahead with his plan after Donoghue told the former president he and others in the departments leadership would resign if he did so.
