Listhaug claimed she was not responsible for the plans, which were designed to make Oslo a prime example for other municipalities in regards to care for the elderly. Listhaug told reporters from the state broadcaster NRK in March 2010 that she did "not have the responsibility for the construction of the nursing home nor authoring the contracts".
