“We will show evidence of the president’s involvement in this plan,” Democratic Rep. Adam Siff, a member of the House of Representatives Select Committee, told CNN’s State of the Union. “We will show again what his own lawyers think about this plan and we will show courageous state officials who stood up and said that they would not go along with this plan either to call the legislatures again to a meeting or to annul the results. “For Joe Biden,” he said.

The evidence against Trump could potentially be crucial in an ongoing criminal investigation by the Department of Justice (DOJ) into the alleged fraudulent voter conspiracy. In an interview with CNN earlier this year, Deputy Attorney General Lisa Monaco confirmed that the department had received references to alternative fake voter plates sent to the National Archives and said prosecutors were examining them. In March, the nonprofit American Oversight released copies of fake ballots collected by groups of Trump supporters in Arizona, Georgia, Michigan, New Mexico, Nevada, Pennsylvania and Pennsylvania. Since then, the Ministry of Justice has convened a large jury to summon witnesses and documents as part of the investigation, several media outlets reported. Jamie Ruskin, another Democratic member of the committee, told NBC’s “Meet the Press” on Sunday that new information and advice was still coming. “There are still people handing over information to the committee,” he said. “We know things this weekend that we did not know last weekend.” Last week, the Ministry of Justice renewed a requirement from the Parliamentary Select Committee to hand over copies of interviews with witnesses, saying in a letter that these copies could be related to ongoing criminal investigations and prosecutions. The commission’s failure to hand them over “complicates the department’s ability to investigate and prosecute those involved in criminal behavior,” the letter said. Asked about the letter on Sunday, Sif said that usually the two separate parts of the government do not allow each other to “run” each other’s files. However, he added: “When the Ministry of Justice asks for specific things … We are working with them, and we will work with them here.” Trump, meanwhile, has continued to spread false allegations that the 2020 election was stolen. On Friday, he attacked former Vice President Mike Pence, saying he “did not have the courage to act” and reject the 2020 election results. On Sunday, Adam Kinzinger, one of two Republicans serving on the committee, said he had received death threats against himself, his wife and their baby. “This threat came in at my house,” he told ABC’s “This Week.” “We took it a few days ago and it threatens to execute me, as well as my wife and my five-month-old child. I have never seen or heard of such a thing,” he added. Sign up now for FREE unlimited access to Reuters.com Register Report by Sarah N. Lynch? additional report by Kanishka Singh.
