But he also found that Comey did not exhibit political bias or try to influence the election, nor did Horowitz contest the decision not to charge Clinton with a crime. However, ultimately after reviewing their messages and their actions, investigators concluded that Page's and Strzok's opinions did not influence their actions at the Federal Bureau of Investigation.
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.
The DoJ report found no evidence to support Trump's claim that Comey was motivated by political bias.
Trump himself said he had "reservations" about a sit-down with the investigators.
"The top people were terrible", Trump said. Trump has repeatedly said there was no collusion or attempt by him to obstruct the Russian Federation investigation, and has called Special Counsel Robert Mueller's probe a "witch hunt".

However, despite backing down, pro-Remain Tories signalled they would not be easily consoled by a compromise offered by ministers. Brexit Secretary David Davis urged MPs to "respect the result of the referendum" that approved the withdrawal.
By Trump's own "partisanship equals bias" logic, these people should be helping him rather than investigating him.
DOJ Inspector General Michael Horowitz wrote that he found Comey's use of personal email to be "inconsistent with Department policy", citing what he called "the absence of exigent circumstances and the frequency with which the use of personal email occurred".
During the investigation, Clinton had maintained her use was appropriate and that other high-ranking US officials had engaged in similar practices involving personal communication devices.
Trump referenced that comment in his tweet Friday and adds: "Doesn't get any lower than that!"
For example, Peter Strzok wasn't going to stop Trump from being elected by anything having to do with the Clinton investigation, which was already over by August 2016. "No he won't. We'll stop it". While Republicans blasted his initial decision to exonerate Clinton, Democrats blamed the former FBI director for costing them the presidential election by reopening the investigation so close to the election.
