Shortly after the first of the 22 March 2016 Belgian bombings, Pearson suggested that the attacks were a justification for the Brexit cause in the then-upcoming referendum on Britain's membership of the European Union, writing on Twitter that "Brussels, de facto capital of the EU, is also the jihadist capital of Europe. And the Remainers dare to say we're safer in the EU!". Her tweet was criticised by Kay Burley and "The Guardian" columnist Owen Jones. Following the May 2017 Manchester Arena bombing, Pearson called for the introduction of internment camps in the United Kingdom.
