After her future husband stepped down as leader of the KRFU in 2002, Hansen was elected deputy representative to the Parliament of Norway from the Vestfold constituency, and served from 2001 to 2005.

[3] A young and active member at the time, she was promoted to leader of the party's youth wing, the KRFU, with her predecessor Per Steinar Osmundnes being elected to Parliament later that year.

[5] In an interview for the national newspaper Aftenposten, Hansen argued that KRF's "unquestionable support" towards Israel and their actions in the Middle East should change rapidly.

As such she condemned the construction of the Israeli West Bank barrier alongside the city of Jerusalem,[6] criticised plans to move the Norwegian Embassy in Israel to the occupied territories that belong to the Palestinians and questioned if Norway should cut off financial support if an agreement between the two nations is not reached.

Hansen also criticised the conservative direction of the party,[7] and claimed that they should support LGBT rights, same-sex marriage and Norway to enter the European Union.

However, the controversy was well received by many as well, with Hansen being recognized as a leading member of the liberal wing that could shape a new and modern Christian Democratic Party.

In contradiction to the Christian Democratic Party's policies, Hansen has opted for a more negative attitude towards the State of Israel such as condemning the construction of the Israeli West Bank barrier.
