"So I guess, it was interesting, it was a pretty good report, and then I say the IG blew it at the very end", Trump told Fox News co-host Steve Doocy of "Fox and Friends" during an impromptu interview on the north lawn of the White House.
The report, released Thursday, faults a number of FBI and DOJ officials for their conduct relating to the investigation into Clinton's use of a private email server when she served as secretary of state.
TRUMP: "I mean there was total bias".
"From what you've seen so far, should James Comey be locked up?"
Mrs Clinton has since said that Mr Comey's letter contributed to her unexpected defeat by Mr Trump.
A long-serving law enforcement official, Mr Comey became a controversial figure in the 2016 election, drawing accusations from both Republicans and Democrats that his handling of an investigation into Mrs Clinton's emails influenced the campaign.
Comey, whom Trump fired shortly after taking office, bore the brunt of much the report's criticism. It also said some FBI agents showed anti-Trump bias, but that bias did not affect the investigation. The firing, in part, kicked off the appointment of Special Counsel Robert Mueller to look into Russia's interference in the 2016 election and whether Trump obstructed an investigation of it.
Trump said on Friday, as he has before, that the Mueller probe, too, "has been totally discredited". Trump is certain to try to use the report to validate his firing of Comey a year ago.More news: Kawhi Leonard wants to be traded; 'uncomfortable' with Spurs
Trump himself said he had "reservations".
The inspector general's report did note that the texts display "a willingness to take official action to impact a presidential candidate's electoral prospects". He asked: "Why would he get interviewed by a corrupt investigation?"
Sessions said Friday "we're not going to be defensive" about the report's findings, but work to "reaffirm and recommit ourselves to the highest ideals" of the Federal Bureau of Investigation.
President Trump declared victory Friday regarding the revelations in the Department of Justice inspector general report. Most notably, Horowitz wrote that Strzok forwarded an email to his personal account regarding a proposed search warrant for former Congressman Anthony Weiner's laptop computer. Yet the most interesting information in his report relates mostly to Russian Federation.
The report said that there was no evidence that either ever acted on their sentiments, but assailed both for "extremely poor judgment and a gross lack of professionalism".
"The report also resoundingly demonstrates that there was no prosecutable case against Mrs Clinton, as we had concluded", Comey wrote.
"But my emails", she said, reacting in a three-word tweet.
