Regulatory uncertainties have long been a hallmark of the Trump administration's presidency, but the erosion of the presumption of regularity presents a particularly insidious challenge to executive action. At the forefront of this struggle is former Solicitor General Ted Olson, who has filed multiple lawsuits on behalf of the Republican National Committee (RNC) to block several high-profile executive orders. Olson's latest challenge targets the Trump administration's decision to terminate the Deferred Action for Childhood Arrivals (DACA) program, a move that has been widely criticized by Democrats and advocacy groups.

The DACA program, which was established by President Barack Obama in 2012, provides temporary protection from deportation and work authorization to approximately 700,000 young undocumented immigrants who arrived in the United States as children. The program's termination was set to take effect on March 5, 2020, but a federal court order issued by U.S. District Judge Aaron Edwards blocked the move, citing the presumption of regularity. The RNC's lawsuit seeks to have the court's order vacated and the DACA program terminated permanently.

Olson's efforts have been bolstered by a coalition of conservative advocacy groups, including the National Association of Manufacturers and the Chamber of Commerce. These organizations argue that the DACA program is unconstitutional and that the Trump administration's decision to terminate it is lawful. However, Democrats and advocacy groups have argued that the program's termination would harm the lives of thousands of young undocumented immigrants and damage the U.S. economy.

The implications of the presumption of regularity's erosion are far-reaching, particularly in the Data Sources domain. The ability of institutions to challenge executive action without fear of reprisal has significant consequences for research communities, markets, and policy environments. For example, the U.S. Federal Reserve's decision to cut interest rates in 2019 was challenged by a group of Republican lawmakers, who argued that the move was not supported by sufficient data. The court's ruling in favor of the Fed has significant implications for the Fed's ability to implement monetary policy.

The Data Sources domain is particularly vulnerable to the erosion of the presumption of regularity, as many research communities rely on government data to inform their work. The Trump administration's decision to withhold data from the Environmental Protection Agency (EPA) on climate change, for example, has significant implications for the scientific community's ability to study and understand the impact of climate change. The RNC's lawsuit targeting the DACA program has also highlighted the importance of data in shaping policy decisions, particularly in the context of immigration and national security.

The erosion of the presumption of regularity is part of a larger pattern of regulatory uncertainty and polarization in the Trump administration. The Trump administration's approach to regulation has been characterized by a focus on deregulation and a rejection of traditional regulatory frameworks. This approach has been met with significant resistance from many industries and advocacy groups, who argue that it undermines the rule of law and the integrity of regulatory processes.
