The activity came just before Congress’ Jan. 6 select committee was set to begin a public hearing expected to scrutinize Clark and other allies of the former president. That hearing was originally set for June 15 but was postponed. Select panel members, including Rep. Zoe Lofgren (D-Calif.), attributed the delay to challenges involved in producing videos for that and other sessions.

Former DOJ officials, including Trump’s acting Attorney General Jeffrey Rosen and his deputy Richard Donoghue, have previously testified that Trump sought to install Clark atop DOJ during the final chaotic days of his administration as part of an effort to use the department to legitimize his false claims of election fraud.

Vought tweeted that the raid on Clark’s house was “[a]ll because Jeff saw fit to investigate voter fraud. This is not America, folks.” He also wrote that his organization stands with Clark, and that the raid is part of a “new era of criminalizing politics” in the U.S.

Clark, now a senior fellow at the group where Vought serves as president, headed DOJ’s Environment and Natural Resources Division for much of the Trump administration. ABC News first reported that federal agents searched Clark’s home in Lorton, Va., on Wednesday morning.
