While scholarship on the US Congress emphasises increasing levels of party unity in the late twentieth and early twenty-first century, recent experiences of the Republican Party in the House of Representatives indicate a divided and rancorous party caucus. The role of Representatives on the right of the Party, in the forms of both the House Freedom Caucus and specific individuals, has been highlighted in coverage of the conflicts. This chapter examines the rise of the Caucus, highlighting its strategy and institutionalisation as a means to achieve a degree of independence from the party leadership. By examining the Caucus’ legislative activities and public communication, its successful navigation of the first Trump presidency is explained, while challenging the received narrative that the Caucus simply became devoted followers of Trump. Finally, the chapter addresses the rise of “celebrity” legislators on the right since the end of Trump’s first term, and the consequent difficulties for the Caucus. The work emphasises the institutional changes that have not just allowed, but incentivised, those on the right to pursue divisive behaviours in pursuit of their agenda and power within the party. Notably though, the Caucus’ influence has been demonstrated to be highly contingent, as their strategies adopted under the first Trump presidency sowed the seeds of later problems among the rise of celebrity legislators on the right.
