Abstract Using the methodology of conversation analysis and a modified analytical framework, this article attempts to characterize and investigate Trump’s practices to resist the agendas of the interviewers’ questions during the press briefings held by the Trump Administration in 2020. Statistical data show that Trump mainly used four types of overt resistant response practices in order of decreasing frequency: (1) Justifying the resistance; (2) Providing a partial answer; (3) Flatly refusing to answer without any explanation; and (4) Resorting to a personal attack, which is a new type of overt resistant practices. However, only one type of covert resistant response practice is identified, i.e. Repeating words subversively. The potential reasons for Trump’s use of such practices are discussed. In essence, Trump’s deliberate use of resistant response practices is a typical reflection of the right-wing populist politicians’ claim of “authenticity” rather than “truth” in the Post-Truth era.
