FBI Director Kash Patel faced pointed questions Tuesday during a Senate Judiciary Committee hearing after whistleblower records were released showing the Bureau’s targeting of Republican organizations under an operation called “Arctic Frost.”
Sen. Chuck Grassley (R-Iowa) led the questioning, citing internal records that suggested the investigation went far beyond President Donald Trump.

Grassley detailed that Arctic Frost, initiated by FBI Agent Thibeau, was later used as a foundation for Special Counsel Jack Smith’s elector case against Trump.
“At your nomination hearing, I made public records that whistleblowers provide me about Arctic Frost,” Grassley said.
“Arctic Frost was the FBI case opened and approved by anti-Trump FBI Agent Thibeau. Arctic Frost then became Jack Smith’s elector case against then-citizen Trump and now-President Trump.”
According to Grassley, newly obtained documents demonstrate that the scope of Arctic Frost was significantly larger than previously understood.
“The case was expanded to Republican organizations,” Grassley said.
“Some examples of the group that Wray and FBI sought to place under political investigation included the Republican National Committee, Republican Attorney General’s Association, and various Trump political groups.”

Grassley told the committee that in total, 92 Republican targets were placed under the investigative scope of Arctic Frost.
“On that political list was one of Charlie Kirk’s groups, Turning Point USA,” he added.
The Iowa senator argued that the evidence showed the FBI was not simply investigating Trump but using the probe to weaken Republican political operations.
“In other words, Arctic Frost wasn’t just a case to politically investigate Trump,” Grassley said.
“It was the vehicle by which partisan FBI agents and Department of Justice prosecutors could achieve their partisan ends and improperly investigate the entire Republican political apparatus.”
Grassley noted that the information is now being made public.
“So today, Sen. Johnson and I are making these records public for the entire country to see, and I hope a lot of people are interested in seeing what government can do when various agencies have a political agenda,” he said.
The hearing also addressed the prosecution of former Trump adviser Peter Navarro. Grassley said his investigation revealed bias within the Bureau.
“My investigative work has also exposed the political way in which Peter Navarro was investigated and prosecuted,” he said.
Grassley cited one FBI agent’s reaction to Navarro’s charges: “When FBI Agent Thibeau found out that Biden’s DOJ would prosecute Navarro, he said, ‘Wow, great.’ That’s a quote-unquote.”

The Judiciary Committee session highlighted concerns about the integrity of federal investigations, with Republicans pressing Patel on what steps the FBI would take to address claims of politicization.
The revelations about Arctic Frost, Grassley argued, demonstrate how investigative powers can be misused when influenced by political motivations.
The inclusion of groups such as the Republican National Committee and Turning Point USA in FBI records has drawn attention to the breadth of the operation.
Lawmakers emphasized that the findings point to potential misuse of federal resources for partisan objectives.
The documents released by Grassley and Sen. Ron Johnson (R-Wis.) are expected to prompt further scrutiny into the FBI’s conduct.
Members of the committee indicated they would continue pressing for accountability and transparency regarding the scope and purpose of Arctic Frost and related cases.
The disclosures underscore an ongoing debate in Washington about whether law enforcement agencies have acted independently or engaged in politically motivated actions against Republican officials, organizations, and individuals connected to Trump.
