"But there’s a bureaucratic coup against President Trump being discovered here," Graham added, saying people in the FBI tried to "taint the [2016 presidential] election" and tip it in Democratic presidential candidate Hillary Clinton Hillary Diane Rodham ClintonDemocratic groups using Bloomberg money to launch M in Spanish language ads in Florida The Hill's Campaign Report: Presidential polls tighten weeks out from Election Day More than 50 Latino faith leaders endorse Biden MORE's favor.

"I don't know what Rosenstein did, but I know what [Andrew McCabe Andrew George McCabeGraham: Comey to testify about FBI's Russia probe, Mueller declined invitation Barr criticizes DOJ in speech declaring all agency power 'is invested in the attorney general' GOP votes to authorize subpoenas, depositions in Obama-era probe MORE] or [Peter Strzok] and [Lisa Page] did," Graham said, alluding to former FBI officials.

Many conservatives have zeroed in on text messages exchanged between Page and Strzok during the 2016 election as evidence of bias against Trump inside the agency.

"They tried to destroy this president," Graham said.

An inspector general report found that the FBI was not affected by bias in its current investigation of Trump and past investigation of Clinton.

"If Rosenstein's involved, he should be fired. If he’s not involved, leave him alone," Graham continued. "But he can’t make that decision. We need a special counsel to look at this. Rosenstein is doing the country a great disservice by not appointing a special counsel to look at all of this."

On Friday, The New York Times reported that Rosenstein proposed secretly recording conversations with the president and discussed the possibility of administration officials invoking the 25th Amendment to remove him from office.

Rosenstein has issued multiple statements disputing the reporting of the Times's story.
