Mr Wray's confirmation hearing took place amid continuing controversy over the Trump administration's links with Russia, following confirmation by Donald Trump jnr that he attended a meeting with a Russian attorney under the pretext of receiving incriminating material on Ms Clinton from the Russian government.
Wray, who appeared likely to win confirmation, said he had no reason to doubt USA intelligence findings that Russian Federation interfered with the election.
Initially, Trump cited a letter from the deputy attorney general detailing Comey's handling of the Clinton email investigation. The position is vacant only because James Comey was sacked over the FBI's investigation into alleged Russian interference in the presidential election and possible collusion with the Trump campaign and associates.
Last month, Mr Comey told a congressional hearing that Mr Trump had requested a pledge of loyalty to him, which Mr Comey said he had refused to give.
He also said he has never discussed Comey's firing with the White House. "My commitment is to the rule of law, to the constitution, to follow the facts wherever they would lead".
Trump fired the respected director of the Federal Bureau of Investigation James Comey in May, expressing frustration about the ongoing investigation into whether his presidential campaign colluded with an alleged Russian effort to tilt the election in his favor. "I would be pleased to do anything I could to support him [in his investigation]".
Feinstein says she wonders, "Will Mr. Wray and the FBI pursue investigations with independence and vigor, regardless of who may be implicated?"
The ripple effect of the Avery Bradley-Marcus Morris trade
So the Pistons have probably lost two starters to get one. and that one can be an unrestricted free agent in 12 months. According to The Vertical's Shams Charania , the Celtics are trading Avery Bradley to the Pistons for Marcus Morris .
Mateja also told IJR he thought it was odd that Trump picked someone like Wray to replace Comey.
OTHER ACCOMPLISHMENTS: As head of the Justice Department's criminal division, Wray oversaw major criminal prosecutions - such as the special task force investigating the Enron collapse - and he also helped shape the US government's legal response to terrorism and national security threats after the terrorist attacks of September 11, 2001.
Graham grilled Wray on how he would lead the department following recent high-profile events, including the June 2016 emails between Donald Trump Jr., the president's eldest son, and acquaintance Rob Goldstone, a music publicist with ties to a prominent Russian oligarch.
Wray hedged, saying he was unfamiliar with the emails, so he wasn't in a position to speak to it.
"To anyone who thinks I would be pulling punches. sure doesn't know me very well", he added. At this time, Wray was part of a team tasked with protecting national security in the wake of the September 11 attacks.
Wray served in the Justice Department during the Bush era from 2001 until 2005 before returning to private practice in Atlanta as a lawyer specializing in white-collar investigations. Chuck Grassley, the committee chairman, and Sen.
So expect Wray to be asked a couple of times about his loyalties and independence.
