On 19 August, citizens of Moscow gathered around Russia's White House and began to erect barricades around it, in which at 16:00 Yanayev responded by declaring a state of emergency in Moscow. Yanayev declared at the press conference at 17:00 that Gorbachev was "resting". He said: "Over these years he has become very tired and needs some time to get his health back." Yanayev said the Emergency Committee was committed to continuing his reforms. However, Yanayev's weak posture, trembling hands and shaky expressions made his words unconvincing. According to some historians, Yanayev was the most visible and powerful member of the Emergency Committee but was not its mastermind; Kryuchkov has been described as the "heart and soul of the conspiracy". Yanayev only agreed to head the Emergency Committee on 20 August. Along with the other coup leaders, such as Valentin Pavlov and Boris Pugo for instance, Yanayev was dismissed as vice president and later jailed for his crimes against the Soviet state.
