Peter Navarro, President Trump’s former trade adviser, was subpoenaed Thursday by the House Select Subcommittee on the Coronavirus Crisis.

Rep. Jim Clyburn, D-S.C., who chairs the subcommittee, claimed in a memo that Navarro has been uncooperative with lawmakers' requests and that he was more concerned about politics and challenging the 2020 presidential election than the COVID-19 pandemic, according to The Hill.

"Given his central role in the pandemic response, the importance of the Select Subcommittee’s investigation, and his continued refusal to cooperate voluntarily, this subpoena is necessary," Clyburn wrote.

The subpoena demands that Navarro turn over documents to the panel by Dec. 8 and appear before the subcommittee for a deposition by Dec. 15.

Navarro is the second individual subpoenaed by the subcommittee since it was established in April 2020. The first was Steven Hatfill, who is a virologist and former adviser to Navarro.

Navarro condemned the subcommittee's investigation and their subpoena as a "witch hunt," telling The Washington Post, "I will be delivering a case of my new book 'In Trump Time' to members of the committee which explains why this is indeed a witch hunt."

"But it was a mistake for the republic because that man is evil," Navarro said. "Make no mistake about this. He is evil because he was at the American bureaucracy that used taxpayer dollars" to pursue gain-of-function experiments. He was referring to research that seeks to find new ways to fight disease by rendering pathogens more infectious and lethal.
