Ukraine without Kuchma
At a 2001 sitting of the Verkhovna Rada, Moroz made public Mykola Melnychenko’s tapes that alleged the involvement of the top leaders of the state (including President Kuchma) in the murder of famous independent journalist Georgiy Gongadze that provoked the political crisis in Ukraine known as the Cassette Scandal. Moroz was a member of a special board "Forum of national salvation", a representative of a Public Committee of Protection of the Constitution "Ukraine without Kuchma" and later "Rise, Ukraine!" in charge of negotiations with representatives of the regime.
