After Otpor merged into the Democratic Party, Homen set about building a political career there. In 2008, he became state secretary in the Serbian Ministry of Justice working under cabinet minister Snežana Malović, within the government of prime minister Mirko Cvetković. Following the 10 October 2010 mass rioting by the right-wing groups in protest of the Belgrade gay pride parade, standing in front of the Democratic Party headquarters that were attacked by the rioters, Homen went on state-television airwaves, delivering a threatening message to the "hooligans". Speaking to a reporter, Homen said: "I can guarantee you that they'll remember this day because the state's response to this will be chilling". In March 2011, Homen was named the Serbian government's PR coordinator.
