Since January, Grassley and Sen. Ron Johnson, R-Wis., have been publishing records related to Arctic Frost, the investigation launched during FBI Director Chris Wray's tenure that served as the basis for former special counsel Jack Smith to bring criminal charges against Trump related to the 2020 election.
Grassley unveiled a new set of documents during his opening statement on Tuesday that showed numerous Republican-affiliated organizations and people were targeted with subpoenas during Arctic Frost.

Kirk was assassinated last week while speaking during an event at Utah Valley University. He was a prolific conservative activist and his massive organization remains a part of his legacy. Turning Point USA recruited conservative college students and was heavily involved in promoting election turnout. In the aftermath of the 2020 election, Kirk amplified some of Trump's claims about election fraud.
Utah Gov. Spencer Cox and Department of Justice leaders have said the suspect in Kirk's shooting, Tyler Robinson, was driven by leftist ideology but that the investigation remains in an early stage. Authorities said antifascist messaging found on bullet casings, Discord messages and other messages have helped to develop an understanding of Robinson's motive as the investigation continues.
