Cossiga also served as minister on several occasions, most notably as Minister of the Interior. In that position he re-structured the Italian police, civil protection and secret services. Due to his repressive approach to public protests, he has been described as a strongman and labeled "Iron Minister". He was in office at the time of the kidnapping and murder of Aldo Moro by the Red Brigades, and resigned as Minister of the Interior when Moro was found dead in 1978. Cossiga was Prime Minister during the Bologna station bombing in 1980.
