A member of the Nationalist Congress Party, he was forest and environment minister in the government of E.K. Mawlong and then cooperation minister under F.A. Khonglam.
He lost his seat in the state assembly in the February 2003 elections.
On June 27, 2003, he was arrested on charges of maintaining links with the banned militant group Achik National Volunteers' Council.
It may be noted that his name is not particularly curious within Meghalaya, where other local politicians are named Lenin R. Marak, Stalin L. Nangmin, Frankenstein W. Momin, or Tony Curtis Lyngdoh. Hitler Marak told the Hindustan Times: "Maybe my parents liked the name and hence christened me Hitler ... I am happy with my name, although I don't have any dictatorial tendencies."
