The Justice Department Office of Legal Counsel opinion, which was released today, says the whistleblower’s complaint centers on the July phone call between the President and the Ukrainian president, the rough transcript of which was released by the White House earlier today.
The opinion further notes that the intelligence community inspector general said the whistleblower, who is still unknown to the Justice Department, as having "some indicia of an arguable political bias."
Even so, the inspector general determined that the whistleblower's complaint was credible, that Trump's actions could be a violation of the campaign finance law.
Notably, yesterday the General Counsel for the Office of the Director of National Intelligence wrote in a letter to the whistleblower’s attorney, that the whistleblower acted in “good faith.”
“I also want to take this opportunity to state that we have every reason to believe that your client - our IC colleague - has acted in good faith and fully complied with the law,” Jason Klitenic, the general counsel, wrote.
