The report, written by Justice Department Inspector General Michael Horowitz, examined the progress of former FBI Director James Comey's investigation into Hillary Clinton's use of a private server.
Comey was quick to react to the watchdog's findings, saying that he doesn't agree with them, but respects the work of the DOJ inspector.

According to conclusions drawn in the report, former FBI Director James Comey broke the bureau's norms in his handling of the probe, but there was no evidence that his actions before the 2016 election were motivated by political bias.
"While we did not find that these decisions were the result of political bias on Comey's part, we nevertheless concluded that by departing so clearly and dramatically from FBI and department norm," Horowitz stated in his report, adding that Comey used the personal account to conduct official business.

The document also revealed the legality of the meeting between US Attorney General Loretta Lynch and former President Bill Clinton on the tarmac of an airport in June of 2016.
"Although we found no evidence that Lynch and former President Clinton discussed the Midyear investigation or engaged in other inappropriate discussions during their tarmac meeting, we also found that Lynch's failure to recognize the appearance problem created by former President Clinton's visit and to take action to cut the visit short was an error in judgment," the report said.
Reacting to the report release, US Attorney Jeff Sessions stated the it shows substantial mistakes made by leaders within the department.
"The Inspector General’s report reveals a number of significant errors by the senior leadership of the Department of Justice and the FBI during the previous administration," Sessions said in a statement, adding that US Attorney John Huber will continue to review the investigation and provide recommendations.
Michael Horowitz, a DOJ watchdog, launched an investigation into Comey's handling of the Hillary Clinton probe in January 2017, after strong criticism from both Democrats and Republicans regarding the former FBI chief's approach to the Clinton email case.
Comey was conducting the probe into the correspondence of presidential candidate Hilary Clinton, who used a private mail server when she was Secretary of State from 2009-2013.
The former FBI director reacted to the news on Twitter, calling the report's conclusions "reasonable" though saying he disagreed with some.

The report also found FBI agents ignored limits on speaking to the press and improperly received gifts from reporters during the period of the Clinton private server and emails investigation.
"We identified instances where FBI employees improperly received benefits from reporters, including tickets to sporting events, golf outings, drinks and meals and admittance to nonpublic social events," it read.
Moreover, the report said the FBI agents ignored policy that strictly limits employees who are authorized to speak to the media.
Clinton herself couldn't resist taking one more swipe at Comey, who she has consistently blamed for her 2016 loss.
