The White House and the US department of justice (DOJ) learned about a CIA officer’s concerns about President Donald Trump around the same time the individual filed a whistleblower complaint that is now at the centre of an impeachment inquiry, according to an American official and another person familiar with the matter.

The intelligence official initially filed a complaint about Trump’s dealings with Ukraine with the CIA, which then alerted the White House and the DOJ. On August 12, 2019, the intelligence official raised another flag — this time with the intelligence community’s inspector-general, a process that granted the individual more legal protections.

During that time, the inspector-general’s complaint — which centred on Trump’s dealings with Ukraine — remained private. But information about the whistleblower was already making its way through the administration: on August 14, White House counsel John Eisenberg and a CIA official alerted the head of the DOJ’s national security division about the original complaint to the CIA.

John Demers, who leads the national security division, went to the White House the next day to review materials associated with the call. He then alerted people within the DOJ, but it was unclear specifically whom he told.

In the weeks that followed, Demers had discussions with other DOJ officials about how to handle the CIA complaint, according to the person familiar with the matter. It was during that period that the DOJ also received a notification from the intelligence community’s inspector-general about a whistleblower complaint.

The timeline raises questions about how the White House and the DOJ handled the complaint. The administration initially blocked Congress from viewing the complaint, citing presidential privilege, and only released a redacted version of the report to lawmakers this week after the impeachment enquiry had begun.

The House intelligence committee released the complaint on Thursday. The nine-page letter details a July 25 phone call in which Trump presses Ukraine’s leader to help investigate baseless corruption accusations against Democratic rival Joe Biden. The complaint also alleges that the White House sought to “lock down” details of the call by moving it onto a secure, classified computer system.

The complaint also details extensive interactions between Rudy Giuliani, Trump's personal attorney, and Ukrainian officials.

The person familiar with the matter, as well as another person with knowledge of the case, confirmed that the whistleblower was a CIA officer.

AP is publishing information about the whistleblower’s background because the person's credibility is central to the impeachment inquiry into the President. The New York Times first reported that the individual was a CIA officer.

The US official and the two people familiar with the matter spoke to AP on condition of anonymity because they were not authorised to speak publicly.

The whistleblower’s attorney, Mark Zaid, said publishing details about the individual places the person in a dangerous situation, personally and professionally. The CIA referred questions to the inspector-general.
