Since 1983 Hagedorn has been a member of the SPD. From 1991 to 2003, she was a member of the SPD district executive Ostholstein, from 1993 as deputy district chairwoman. From 2003 to 2019 she was a member of the state executive committee of the SPD in Schleswig-Holstein. From 2007 to 2019 she served as deputy state chairwoman of the SPD in Schleswig-Holstein, under the leadership of chairman Ralf Stegner.[2]
From 1986 to 2003 Hagedorn was a member of the municipal council of her place of residence, Kasseedorf, where she also served as a deputy mayor (1994–1997) and mayor (1997–2003).[2]
Throughout that period, Hagedorn also served on the Audit Committee, which she chaired from 2013 until 2017. Both from 2005 to 2009 and from 2013 to 2017, she was a member of the so-called Confidential Committee (Vertrauensgremium) of the Budget Committee, which provides budgetary supervision for Germany’s three intelligence services, BND, BfV and MAD.
In addition to her committee assignments, Hagedorn is a member of the German Parliamentary Friendship Group with the Nordic States. Within her parliamentary group, she has been serving as on the working groups on budgetary policies since 2009 and for municipal policies since 2005. She also belongs to the Parliamentary Left, a left-wing movement.[3]
In 2015, Hagedorn was one of the victims of a large-scale cyberattack on the German Parliament’s computer network.[4]
In the 2017 federal elections, Hagedorn led her party’s list for Schleswig-Holstein.[5] In Chancellor Angela Merkel’s fourth cabinet, she joined the federal government as one of two Parliamentary State Secretaries – alongside Christine Lambrecht (2018-2019), later Sarah Ryglewski (2019–2021) – serving under Finance Minister Olaf Scholz. In this capacity, she participated in the fifth German-Indian government consultations in Delhi in November 2019.
Following the 2021 elections, Hagedorn joined the Budget Committee again, where she has since been serving as her parliamentary group’s rapporteur on the annual budget of the Federal Ministry for Economic Cooperation and Development.
