Whistle-blower timeline.

Sept. 9 — Atkinson, the inspector general of the intelligence community, notifies the House intelligence committee that he received a whistleblower’s complaint relating to an “urgent concern” on Aug. 12. He says he found the information credible, and sent “my determination of a credible urgent concern” along with a copy of the complaint to Acting Director of National Intelligence Joseph Maguire, who had seven days to forward the complaint to Congress. But, contrary to “past practice,” Maguire did not forward the complaint to Congress, believing “the allegations do not meet the definition of an ‘urgent concern’ under the [whistleblower] statute,” Atkinson writes. The inspector general says he will keep the committee apprised of his attempts to resolve the issue.
