The whistleblower who submitted a complaint on possible abuses of power by President Trump originally reported the matter to the CIA general counsel, according to a report from the New York Times.

The CIA lawyer, Courtney Simmons Elwood, then shared the report with the White House and the Department of Justice, following standard procedure with regard to complaints of this type. The whistleblower remained anonymous throughout the process.

Elwood also took up the whistleblower’s concerns with officials from the Justice Department. Eventually Attorney General William P. Barr was made aware of the allegations, but was not involved in planning further proceedings regarding them.

However, during this time, the whistleblower learned that his concerns had been passed on to the White House. He suspected that the CIA wasn’t taking his concerns seriously, so he decided to file a complaint with the intelligence community inspector general, Michael Atkinson, a move that gave him legal protection.
