On January 29, 2022, Cooper attended the proclaimed Freedom Convoy 2022 protest in Ottawa and handed out coffee to participants alongside fellow Alberta Conservative MP Damien Kurek. Cooper was interviewed on-site by CBC News as a convoy protester in the background was seen holding a Canadian flag defaced with a swastika. The interview prompted a joint statement by Edmonton mayor Amarjeet Sohi and St.Albert mayor Cathy Heron declaring that they were troubled by the photograph and that Cooper did not represent the values of their constituents. Later that night, Cooper released a statement saying that he was unaware of the swastika-defaced flag, condemned Nazism as "the purest form of evil" and the decision to fly the flag as "reprehensible", but said it was not representative of the majority of Freedom Convoy protestors.
