Comey additionally expressed that FBI leadership believed Sessions would "inevitably" recuse himself and that they "were aware of facts that I can't discuss in an open setting that would make his continued engagement in a Russia-related investigation problematic".
"Whether you like what Comey did or not", Rather said, "you have to admit he's a great storyteller".
Sessions had previously been scheduled to testify before the Senate and House Appropriations subcommittees Tuesday, but now that he's appearing before the Senate Intelligence Committee, Deputy Attorney General Rosenstein will testify before those panels instead.
Comey said Trump told Sessions and other administration officials to leave the room before Trump asked him in February to drop a probe into former National Security Adviser Michael Flynn's contacts with Russian Federation. At his January confirmation hearing as attorney general, he testified that he had not met with Russian government officials during the campaign.
In addition, Comey has said Sessions did not respond when he complained that he did not want to be left alone with Trump again.

Sessions noted that several lawmakers on those panels had said they meant to ask him about the Russian Federation investigation, after testimony by former FBI director James Comey before the intelligence committee Thursday.

It was later reported that Comey privately told the Senate Intelligence Committee that Sessions was involved in a third undisclosed meeting with Russian officials during the campaign.
Democratic Sen. Dianne Feinstein of California, a member of the Intelligence committee, sent a letter to Sen. Chuck Grassley, R-Iowa, urging him to investigate possible obstruction of justice by Trump in Grassley's position as chairman of the Judiciary Committee. "It would be very good to get it directly from him". "And so there is an opportunity to look at the law with respect to obstruction of justice, to hold a hearing, and also to have those relevant people come before the Judiciary Committee", said Feinstein, who is a member of both committees.
The letter did not say whether Sessions planned to give public testimony on Tuesday or to appear before the panel behind closed doors. Comey testified that Lynch asked him during last year's presidential campaign to call the investigation into Democrat Hillary Clinton's emails a "matter".
Trump at first maintained Comey had been fired as a result of discontent among the FBI agents he supervised, but a day later admitted that he fired the FBI chief as a effect of the bureau's investigation of Russian meddling in US politics. Feinstein said the Judiciary Committee should investigate.
"There's an unpredictability. He projects an instability", Feinstein said.
