Called to face the Commission, Anastasia refused to accept guilt for the Mangano murders. However, Anastasia did claim that Vincent Mangano had been planning to kill him. Anastasia was already running the family in Vincent Mangano's "absence" and the Commission members were intimidated by Anastasia. With the support of Frank Costello, boss of the Luciano crime family, the Commission confirmed Anastasia's ascension as boss of what was now the Anastasia crime family. Carlo Gambino, a wily character with designs on the leadership himself, maneuvered himself into the position of consigliere.
