Born in Bærum on 23 February 1966, Trøen is a daughter of factory manager John Willy Wilhelmsen and secretary Anne-Marie Christiansen.[1] She is married to Ove Trøen, together they have one son.[2][3]
Following Olemic Thommessen's resignation as President of the Storting, she became the Conservative Party's candidate to replace him as President on 14 March 2018. She was formally elected as the day after.[5]
She is the second woman to have served as President of the Storting, the first being Kirsti Kolle Grøndahl of the Labour Party, who served from 1993 until 2001.[6]
In March 2021, the Storting was the victim of a cyber attack. Trøen called it "an attack on our democracy" and noted that the attack had the potential to disturb parliamentary processes.[7]
In September, after several media revelations of MPs misusing parliamentary commuter homes and the severance pay scheme, Trøen announced that the Storting presidency would be looking into the matter. A revelation of the former later lead to the resignation of minister of children and families Kjell Ingolf Ropstad.[8] A few days later, it was also revealed that Trøen herself also had misused her parliamentary commuter home by allowing her son to utilise it as a student dormitory. She argued that nothing in the rules prohibited the home for such usage.[9]
