Faber has been a member of the United Democratic Party of Belize since he worked as a street campaigner at the age of 14. He has since served as youth director, member of the party's central executive, and candidate for the Belize City Council. In 2010, at the National Convention of the United Democratic Party, he was elected overwhelmingly to the role of Party Chairman.
Faber is currently one of the youngest members of the Belizean House of Representatives. According to Belizean media, public confidence in Faber, the Ministry of Education and its restructuring has been positive. Consequently, Sir Colville Young, the Governor General of Belize, entrusted Faber with also running the Ministry of Youth. Faber has even served occasionally as acting prime minister, being responsible for running the affairs of state when the Prime Minister and Deputy Prime Minister are out of the country.[3]
Despite recent political difficulties, Faber will stand as a candidate for UDP party leader in a leadership convention set for 9 February 2020 to succeed the retiring Barrow. His opponent will be Minister of National Security, John Saldivar who is eyeing for the same position as him.[4][5]
Faber previously went against Saldivar in 2010 for Chairman of the UDP and 2016 for first Deputy Leader, winning both times.
In July 2020, Faber was appointed as Leader of the UDP after Prime Minister Dean Barrow stated his plans to retire. In the November General Elections, his party suffered one of the largest losses in its history, losing 14 seats from 19 down to only 5.[6]
