Political scientists seeking to understand politics and policy-making typically startwith what political actors say and do. But Donald Trump's tumultuous presidency reminds us that images also matter. Engaging with methods, concepts and theories from visual studies, this article analyses images of the 45 th president produced by official photographers, photojournalists, political activists and foreign governments between 1985 and 2021. W.J.T. Mitchell's concept of the pictorial turn, it argues, helps us to understand the importance of such images for Trump's post-truth politics, but also anxiety about their influence. This article finds that attempts to deride, deface or destroy Trump's charismatic, strong-man persona were never likely to succeed because, as Mitchell predicts, they reduced the president's supporters to idolaters in thrall to the power of images. Images played a more productive role, this article finds, by debunking the president's political falsehoods in ways that textual corrections struggled to do and by documenting his administration's disruptive approach to policy-making in areas such as foreign affairs and immigration policy. Such images did not tell the whole truth, but they were no less successful at confronting Trump's post-truth politics as a result.
