(DCNF)—Harvard Law professor emeritus Alan Dershowitz said on Fox Business Monday that former special counsel Jack Smith ‘disgrace himself’ for reportedly obtaining private phone records of Republican senators without their knowledge.

Senate Republicans revealed Monday that the FBI used grand jury subpoenas in 2023 to seize phone records from nine GOP senators, calling the move a politically motivated abuse of power. In an appearance on “The Evening Edit,” Dershowitz didn’t mince words.

“The idea of a special counsel intruding on private phone calls without, as far as I know, notifying the recipients of the phone calls. I think that does require a congressional investigation. Jack Smith has disgraced himself,” Dershowitz told host Elizabeth MacDonald.

Dershowitz said Smith’s action is a blatant overreach that tramples constitutional boundaries and warrants immediate congressional oversight.

“Oh, much too far. Have obviously constitutional immunity of a certain kind. Obviously the telephone wasn’t invented at the time of the Constitution,” Dershowitz said when the host asked if the special counsel had crossed a line.

Senate Judiciary Committee Chairman Chuck Grassley released the FBI record Monday, as Republicans stressed the phone records were obtained lawfully through a grand jury process.

“This document shows the Biden FBI spied on eight of my Republican Senate colleagues during its Arctic Frost investigation into ‘election conspiracy.’ Arctic Frost later became Jack Smith’s elector case against Trump,” Grassley said.

Documents released in September show the Biden-era probe that led to Smith’s indictment of President Donald Trump also targeted dozens of conservative groups, including Turning Point USA and the RNC. Grassley said that the FBI’s “Arctic Frost” investigation swept up 92 Republican figures.

Grassley accused the FBI of using the “Arctic Frost” probe to improperly target the broader Republican political apparatus for partisan purposes. (RELATED: ‘How Serious Is It?’: Alan Dershowitz Breaks Down What Punishments Could Await From Students’ Pork Prank)

“Arctic Frost wasn’t just a case to politically investigate Trump,” Grassley said Tuesday during his opening statement for the Judiciary Committee’s FBI oversight hearing. “It was the vehicle by which partisan FBI agents and DOJ prosecutors could achieve their partisan ends and improperly investigate the entire Republican political apparatus.”
