"I can remember like it was yesterday where I was and what I was doing when I learned of these text messages", he told CNN anchor Brooke Baldwin.
The final report, released Thursday, clearly states that "we did not find documentary or testimonial evidence that improper considerations, including political bias, directly affected the specific investigative actions we reviewed".
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.
The DoJ report found no evidence to support Trump's claim that Comey was motivated by political bias. While Horowitz says Comey treated Clinton unfairly, Trump has long argued that Comey let Clinton off easy.
Trump, who has repeatedly called the Russian Federation probe "hoax" or "witch hunt", has ratcheted up pressure on it in the past months.
In the middle of the campaign, Comey announced Clinton would not be prosecuted - a statement that would have normally been handled by the attorney general and drew heavy criticism.
Trump has been eager for the report in hopes that it would vindicate his decision to fire Comey and undermine special counsel Robert Mueller's investigation. "Unfortunately, over the past year, the DOJ has repeatedly fought requests by Congress to produce documents related to this investigation, and when the DOJ actually provided documents, the materials have been heavily redacted". It criticized then-FBI Director James Comey and others for their handling of the Clinton email probe.
"I have never accused him of being a partisan".
FBI Director Christopher Wray said the department will "hold employees accountable for any potential misconduct" in response to the report.
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.
Horowitz concluded in his report that while mistakes were made, there was no bias in the FBI's handling of the Clinton email investigation.
