The senator's body was discovered by housekeeping staff at the Suncadia Resort in Washington state after he failed to check out of his room.
White was at the Cle Elum resort for a leadership conference organized by Seattle Chamber of Commerce. He was on a panel Thursday speaking about ways that the west side of the state and the east side of the state can better work together.
An autopsy is planned to determine how White died. Authorities say there is no evidence of foul play in his death.
The democrat represented Washington state's 46th district, covering the northern parts of Seattle.
He joined the senate last year and rose to serve as majority whip, advocating for transit issues as a caucus transportation leader. He worked most recently as a project manager at the University of Washington.
Scott is survived by a wife and two children.
