In the first 100 days of his second term, President Trump issued 143 executive orders, signaling a rapid and sweeping policy shift. In response, Republican members of the House introduced a substantial number of bills aimed at codifying the content of the executive orders. This paper categorizes President Trump's major executive orders and analyzes the co-sponsorship patterns of corresponding bills, thereby examining how different factions within the Republican Party responded legislatively. The findings reveal distinct factional alignments: Freedom Caucus led efforts on federal downsizing and international aid cuts, and supported strict border control measures. In contrast, crime-related immigration
bills were driven by the centrist Republican Main Street Partnership, while Republican Study Committee championed legislation addressing cultural issues such as abortion and gender. Unlike other areas, energy deregulation saw co-sponsorship patterns shaped less by ideological factions than by the economic composition of individual congressional districts.
