Kromah was a special assistant to the Vice-President and later Assistant Information Minister during the regime of President William Tolbert before becoming Director General of the Liberian Broadcasting System in 1982 and Minister of Information in 1984 under President Samuel Doe and denied the government's crackdown leading to some deaths at the University of Liberia in 1984. He went into exile in June 1990, months after the civil war began in Liberia.
