The Biden-era FBI’s “Arctic Frost” investigation into President Trump and the broader GOP’s role in the January 6, 2021 Capitol riot was more wide-ranging than previously known, according to newly released documents showing the bureau issued nearly 200 subpoenas targeting more than 400 Republican entities and individuals as part of the probe.

Senator Chuck Grassley (R., Iowa) released records on Wednesday showing 197 subpoenas were issued to individuals and businesses during the FBI’s “Arctic Frost” investigation targeting 430 GOP individuals and entities. He obtained the records through protected whistleblower disclosures.

Financial institutions, Trump-aligned political organizations and operatives, conservative think tanks, and payroll companies were among the subpoena recipients, according to a list compiled by the Senate Judiciary Committee. Federal investigators sought communications between the targeted individuals and media companies, prominent Trump-world officials, and legislative staff. The investigative efforts also encompassed MAGA fundraising efforts and donors.

Several GOP members of the Senate Judiciary Committee, the panel Grassley leads as chairman, spoke at a press conference Wednesday afternoon unveiling the new information.

“What is revealed in those 1700 pages of documents, those 197 subpoenas, is nothing short of a Biden administration enemies list,” Senator Ron Johnson (R., Wis.) said.

Johnson said he knew most of the 38 individuals from his state on the Biden administration’s “enemies list” and urged his fellow lawmakers to assist the Trump administration with getting to the bottom of the FBI’s conduct.

“This extended far beyond President Trump and extended to President Trump’s supporters not only here in the United States Senate but more broadly,” Senator John Cornyn (R., Texas) lamented.

“Merrick Garland was a member of Joe Biden’s cabinet. He was willing to do whatever Joe Biden and his political operation wanted him to do, including destroying President Trump,” Cornyn added.

The “Arctic Frost” investigation looked into the role President Trump played in the Capitol riot. The probe eventually morphed into special counsel Jack Smith’s Washington, D.C., criminal case against Trump. Then-Attorney General Merrick Garland and then-FBI Director Christopher Wray personally signed off on the investigation when it was launched in 2022, according to a decision memo Grassley divulged last week.

The “Arctic Frost” investigation has come under Republican scrutiny because of its wide-ranging scope. The FBI targeted eight GOP Senators they believed may have been involved in a scheme to install fraudulent electors to secure Trump’s victory, subpoenaing phone companies for the lawmakers’ toll records , from January 4-7, 2021, which show who a given individual spoke with on the phone but not the contents of their calls. Representative Mike Pelly (R., Pa.) was also mentioned in the FBI records Grassley disclosed.

A ninth GOP Senator, Ted Cruz of Texas, was also targeted during the “Arctic Frost” investigation, Axios first reported. Several of the GOP lawmakers in the FBI’s crosshairs promoted Trump’s false claims about the 2020 presidential election being stolen from him. The attempts by Trump’s allies to contest the 2020 election formed the basis of Smith’s D.C. criminal case and criminal prosecutions in the swing-states Trump lost to former President Biden. Numerous individuals targeted in “Arctic Frost” later faced criminal charges for their failed attempts to overturn the 2020 election results.

“Jack Smith was a fundamentally corrupt prosecutor. This was a political enemies list from the beginning,” Cruz said. “This is an executive who believes it is justified spying on their opponents in the legislature because they convinced themselves the ends justified the means.”

Smith attempted to subpoena AT&T to obtain Cruz’s cellphone communications and the company’s legal counsel declined to comply, Cruz said. He praised the company for standing its ground against Smith’s attempt to gain his phone records. Cruz said that Washington, D.C., federal Judge James Boasberg signed an order prohibiting AT&T from informing Cruz of the subpoena for a year because of the potential for Cruz to destroy evidence or intimidate witnesses.

“This order is an abuse of power. This order is a weaponized legal system,” Cruz said. He speculated that Boasberg issued similar orders for the other subpoenas directed at GOP Senators’ communications.

Grassley previously released records showing the FBI investigation targeted more than 92 Republican organizations and GOP-linked operatives, including the late Charlie Kirk’s Turning Point USA and the Republican National Committee. On Tuesday, the House Judiciary Committee released records indicating the FBI was potentially investigating dozens of GOP operatives and former Trump administration officials.

The House panel’s revelations were similar to disclosures Grassley unveiled in March about the scope of the anti-Trump investigation and the FBI’s acquisition of the government phones used by Trump and former Vice President Mike Pence. The FBI conducted over 40 interviews and collaborated with field offices nationwide to carry out the “Arctic Frost” probe.

In September, FBI Director Kash Patel fired agents in the Washington Field Office and shuttered the unit responsible for conducting the “Arctic Frost” investigation. Patel has worked closely with his Senate and House counterparts to release the FBI records and root out what he considers institutionalized corruption at the bureau.

“Every day this FBI is releasing documents like these to give the public full view of what happened, work with Congress to right the wrongs, and hold accountable anyone who acted unethically – period. Corruption like this is being crushed in your federal government day by day. It's a new era,” Patel posted on X Tuesday.

Grassley continues to conduct oversight on the “Arctic Frost” investigation and other Biden-era FBI scandals that conservatives have scrutinized. He has suggested that “Arctic Frost” may have exceeded Watergate in its severity. He released the records Wednesday in the name of transparency as Republican investigative efforts continue.

Smith’s case against Trump in Washington, D.C., was delayed significantly by litigation that resulted in the Supreme Court’s decision last year granting the president criminal immunity for official acts. Smith folded the D.C. case and his classified documents case in Florida upon Trump’s victory in the 2024 presidential election.

Trump routinely accused Smith of weaponizing the federal government against him during the prosecutions. Smith resigned after ending his cases instead of giving Trump the pleasure of firing him.

“These thugs should all be investigated and put in prison. A disgrace to humanity. Deranged Jack Smith is a criminal!!!” Trump posted Wednesday on Truth Social.

Smith has offered to testify publicly before the House Judiciary Committee to defend his record from what he argues are unfounded Republican attacks. His attorneys have defended the “Arctic Frost” investigation’s decision to obtain the phone records of GOP Senators as lawful activity permitted under Justice Department policy.
