“Arctic Frost was the vehicle by which partisan FBI agents and DOJ prosecutors could improperly investigate the entire Republican political apparatus,” Grassley said during a press conference Wednesday. “Contrary to what Smith has said publicly, this was clearly a fishing expedition.”

Smith issued the subpoenas as part of his 2020 election interference case against President Donald Trump, which was dropped along with the classified documents case when Trump won the election.

Republican Wisconsin Sen. Ron Johnson said the subpoenas, which Grassley’s office released here, show “nothing short of a Biden administration enemies list.”

Johnson noted the records were obtained through a whistleblower, not the agency, urging more whistleblowers to come forward. FBI Director Kash Patel and Attorney General Pam Bondi are “overwhelmed by all the messes they’re trying to clean up” and short-staffed, Johnson said.

“I don’t think they have control,” Johnson said of Bondi and Patel. “I think they’re being sabotaged within.”

Information requested from individuals who faced subpoenas included communications with “any member, employee or agent of the Legislative Branch of the U.S. Government,” as well as with media companies and White House advisors.

“These thugs should all be investigated and put in prison,” Trump wrote on Truth Social after the press conference. “A disgrace to humanity. Deranged Jack Smith is a criminal!!!”

Republican Missouri Sen. Eric Schmitt said he couldn’t think of “a bigger political scandal in the last 100 years.” Republican Tennessee Sen. Marsha Blackburn called it “worse than Watergate.”

Grassley previously revealed that cell phone records from nine Republican Members of Congress were subpoenaed as part of Smith’s investigation.
