Trump has also been reported to be privately unhappy at the attorney general's move to recuse himself from recent investigations which are looking into Russian Federation possibly meddling in last year's presidential elections, according to sources. Shelby chairs the Senate appropriations subcommittee.
Sessions is due to testify on the Justice Department's budget request on Tuesday in both the House of Representatives and Senate.
"Jeff could add a lot of light to it as to why he recused himself", said Senator Joe Manchin, a West Virginia Democrat and member of the Senate Intelligence Committee."There's one meeting we don't know about, and people would like to know about it". In his testimony Thursday, Comey said even before Jeff Sessions recused himself the Federal Bureau of Investigation thought he would, citing facts Comey couldn't discuss in public that would hurt Sessions' ability to oversee the Russian Federation case. "The Senate Intelligence Committee is the most appropriate forum for such matters, as it has been conducting an investigation and has access to relevant, classified information".
Sessions remains at the Justice Department, where a spokeswoman told CNN that he is not stepping down.
United States Attorney-General Jeff Sessions had suggested in the past few weeks that he might resign amid a widening rift with President Donald Trump, according to a person familiar with the matter.
He told Shelby that the Russian Federation investigation would very likely be the focus of the Intelligence Committee's questioning.
Rosenstein was also involved in Comey's firing and wrote a memo about Comey for Trump.
Comey said he also told Sessions that he was concerned about being alone with Trump, and Sessions did not say or do anything in response. When reporters asked Spicer if Trump had lost confidence in Sessions, Spicer said, "I have not had a discussion with him about that". Mr Trump fired Mr Comey later that day. Yet, less than a month after taking office as Attorney-General, Mr Sessions found himself at the centre of controversy following reports that he had failed to disclose during his confirmation hearings two conversations he had past year with Russian ambassador Sergey Kislyak.
