In 2015, he started the political party We Are Family (Slovak: Sme Rodina). His party won 11 seats to the National Council during the 2016 Slovak parliamentary election.
In 2016, a source turned over to SME material linking Boris Kollár to the Slovak mafia. Kollar rejected the accusation as an attempt to discredit him.
