In August 2017, Bishop contributed $500 toward the establishment of the social network Gab, a website criticized for its white supremacist and far-right content. He said he made the contribution in response to what he called a California "tech giants' Big Brother routine", referring to companies such as PayPal and Facebook canceling accounts used by organizers and funders of the Unite the Right rally, in Charlottesville, Virginia. Bishop's crowdfunding contribution attracted attention the next year, after the Pittsburgh synagogue shooting. He responded that he was being "smeared", saying, "I don't use Gab, but if its management allows its users to promote violence, anti-Semitism, and racism on the platform they have misled investors and they will be gone quickly, and rightfully so." The contribution came up again a week after the 2019 El Paso shooting and a month before Bishop's House election. A group called Stand Up Republic aired criticism of his contribution to Gab as part of a $500,000 advertising campaign. Bishop criticized the advertising, calling it "defamatory".
