The report, the IG report was a horror show.
"The IG Report is a total disaster for Comey, his minions and sadly, the FBI", Trump said in a post on Twitter. That Comey, of all people, engaged in the same actions that consumed her campaign will go down in history as one of the great twisted ironies of our time.
Trump himself said he had "reservations".
President Trump has looked to the report to provide a fresh line of attack against Comey and his deputy, Andrew McCabe, as he claims that a politically tainted bureau tried to undermine his campaign and, through the later Russian Federation investigation, his presidency.
Perhaps even more hard to swallow for Clinton and her supporters, however, is the IG's finding that Comey himself used a private email account while at the Federal Bureau of Investigation.
The report also rebuked Comey for disclosing just days before the election that the Federal Bureau of Investigation was reopening the Clinton case to review hundreds of thousands of newly-discovered emails - emails that turned out to be of little outcome.
Among Comey's missteps during the Clinton email investigation was his decision in July 2016 to publicly call for Clinton's exoneration before the probe had concluded; followed by his revelation to Congress weeks before the election that the FBI had reopened its investigation.
"We are concerned that during this time, people may have changed the report in a way that obfuscates your findings", they wrote.
The findings have no direct bearing on a separate Justice Department special counsel probe on Russia's alleged interference in the election, and the possibility there was collusion between the Trump campaign and Moscow.
Those text exchanges caused the inspector general to evaluate whether any of Strzok's decisions were affected by political considerations, and raised concerns that there was a "willingness to take official action to impact the presidential candidate's electoral prospects".
The report may give rise to the debate over the extent to which Comey's actions secured Trump's victory.
The Justice Department has also issued a stinging rebuke to the FBI for its handling of the email investigation. Clinton and some Democrats have argued Comey's handling of the probe cost Clinton the election. First the "delete your account" meme, and now "but her emails".
Trump has suggested anyone less politically connected than Clinton would have been charged for the same behavior, yet the report does not second-guess the FBI's decision to spare her from prosecution.
