CNN justice reporter Laura Jarrett said Monday FBI Peter Strzok was the person who changed then-FBI Director James Comey's language on Hillary Clinton's actions, in regard to handling classified materials on her private server, from "grossly negligent" to "extremely careless." "Over the weekend, we learned that this top counterintelligence expert was removed by Mueller after exchanging text messages that appeared to mock President Trump. And now, CNN reporting breaking right now on the agent's role in the Hillary Clinton e-mail probe," CNN's Jake Tapper reported. "Well, Jake, sources we have learned from tell us that the electronic records show that Peter Strzok changed former FBI Director James Comey earlier draft language describing Clinton's actions in handling classified materials from, quote, 'grossly negligent' to 'extremely careless,'" reported CNN justice reporter Laura Jarett. From Monday's broadcast of CNN's <i>The Lead with Jake Tapper</i>: <blockquote>JAKE TAPPER, CNN HOST: We have some breaking news now in the politics lead. New information about the FBI agent dismissed from Robert Mueller's special counsel investigation. Over the weekend, we learned that this top counterintelligence expert was removed by Mueller after exchanging text messages that appeared to mock President Trump. And now, CNN reporting breaking right now on the agent's role in the Hillary Clinton e-mail probe. I want to bring in CNN's Laura Jarrett. And, Laura, records show messages by this agent raised questions about whether or not justice was truly blind in the investigation into Hillary Clinton. LAURA JARETT, CNN JUSTICE REPORTER: Well, Jake, sources we have learned from tell us that the electronic records show that Peter Strzok changed former FBI Director James Comey earlier draft language describing Clinton's actions in handling classified materials from, quote, "grossly negligent" to "extremely careless". Now, this entire drafting process was a team effort at the FBI, we're told. As we reported last month, after the news surfaced that the language had, in fact, been softened, that Comey and his colleagues had been playing with the language for some time. But that identity of the person who actually made the change had not been known until now. Take a listen to what Comey said clearing the former secretary of state back in 2016. (BEGIN VIDEO CLIP) JAMES COMEY, FORMER FBI DIRECTOR: Although we did not find clear evidence that Secretary Clinton or her colleagues intended to violate laws governing the handling of classified information, there is evidence that they were extremely careless in their handling of very sensitive, highly classified information. (END VIDEO CLIP) JARRETT: Now this key shift from grossly negligent to extremely careless may seem like mere semantics but it actually reflects a decision that the FBI could have had a potentially serious legal implication here as the federal law that actually governs the handling of classified materials establishes criminal penalties for gross negligence. So, the change there actually is legally significant, but from an optics standpoint, certainly the news obstructs direct role in this statement that ultimately cleared Clinton, combined with the fact that he was dismissed from special counsel Robert Mueller's team after exchange private messages with an FBI lawyer could be seen as favoring Clinton politically. It may now give further ammunition to those seeking ways to discredit special counsel Robert Mueller's probe, Jake. </blockquote>
