Vasciannie was one of the founding members of the
National Democratic Movement (NDM) along with former Prime Minister of Jamaica
Bruce Golding. He served as Deputy Solicitor-General until 2007. The Public Services Commission recommended that year that he be appointed Solicitor-General, however, Golding, whose relationship with Vasciannie had deteriorated since Golding's departure from the NDM, did not accept Vasciannie's nomination; instead, Golding fired all the members of the commission, and the new commission members appointed chose
Douglas Leys to assume the office of Solicitor-General instead. Preceding the People's National Party victory in the 2012 general election Vasciannie was named Jamaica's ambassador to the United States in June 2012, and succeeded Jamaican businesswoman
Audrey Marks, who was appointed under the Golding administration. ==Other activities==
