President Trump tore into Jack Smith as “a real sleazebag” following stunning revelations that the FBI obtained phone records of eight Republican senators under the former special counsel’s watch.

As a part of the Biden administration’s “Arctic Frost” probe helmed by Smith, the FBI conducted a “preliminary toll analysis” on the GOP lawmakers in 2023, a bombshell document released by Sen. Chuck Grassley (R-Iowa) on Monday revealed.

“Deranged Jack Smith got caught with his hand in the cookie jar. A real sleazebag!!!” Trump chided on Truth Social.

Smith had led the Justice Department team that slapped Trump with 44 felony counts across two separate indictments, including the Mar-a-Lago document debacle and the 2020 election interference case.

Arctic Frost was the bureau’s probe into 2020 election interference concerns. 

The probe launched in April 2022 and Smith took it over later that year.

Lawmakers targeted by the bureau were Sens. Lindsey Graham (R-SC), Bill Hagerty (R-Tenn.), Josh Hawley (R-Mo.), Dan Sullivan (R-Alaska), Tommy Tuberville (R-Ala.), Ron Johnson (R-Wis.), Cynthia Lummis (R-Wyo.) and Marsha Blackburn (R-Tenn.), as well as Rep. Mike Kelly (R-Pa.), according to the document released by Grassley.

GOP senators said they had no idea what grounds the FBI had to allegedly spy on them. The agency is believed to have looked at phone records such as who called who and at what time, rather than actually tapping in on calls, according to Johnson. 

The one-page document released Monday was a Sept. 27, 2023, file titled “CAST Assistance,” which refers to the bureau’s cellular analysis team.

It indicated that the bureau had finished a “preliminary toll analysis on limited toll records.”

FBI Director Kash Patel’s team discovered the document after an employee attempted to get recertified for the bureau’s CAST system and cited it as an example of how the program was used in the past, Johnson told reporters. 

GOP senators were furious about the revelation and announced plans to investigate the matter. 

“Based on the evidence to-date, Arctic Frost and related weaponization by federal law enforcement under Biden was arguably worse than Watergate,” Grassley said in a statement. 

“If heads don’t roll in this town, nothing changes,” Grassley later grumbled to reporters.

Earlier this year, whistleblowers came forward with accusations that the FBI obtained phone data on Trump and former Vice President Mike Pence as part of the Arctic Frost investigation. 

Last month, it was revealed that the FBI had 92 Republican-linked groups or people, such as Turning Point USA, under Arctic Frost’s investigative purview.

Other documents indicate that the FBI had been using its investigative tools to examine machinations aimed at furnishing an alternative slate of electors to undermine the 2020 election results. 

Since Trump’s return to the White House, his team has been scrutinizing Justice Department officials who were involved with investigations into the 2020 election and Jan. 6, 2021, Capitol riot. 

In August, officials confirmed that the Office of the Special Counsel (OSC) began a probe into Smith.

The former special counsel has maintained his belief that Trump would’ve been convicted had he not been reelected.
