In his first 100 days back as president, Donald J. Trump has embarked on a series of controversial actions that legal scholars contend are lawless and potentially unconstitutional. These include an attack on birthright citizenship, a disregard for due process in deporting individuals, and exerting pressure on law firms, universities, and the press. His administration's actions demonstrate a significant push towards consolidating presidential power, challenging the separation of powers and civil liberties. Despite these moves, some actions remain within presidential authority, though their rapid implementation raises concerns about the erosion of democratic norms. The overall trajectory suggests a potential authoritarian shift, prompting calls for robust political opposition and legal reforms to safeguard constitutional democracy.

Trump's executive order to end birthright citizenship, deemed unconstitutional by legal scholars, has led to a series of legal challenges and temporary court injunctions. This move signals an effort to overturn long-established rights and Supreme Court precedents, reflecting a broader agenda to challenge constitutional norms.

The administration's deportation policies, exemplified by the case of Kilmar Armando Abrego Garcia, highlight a disregard for due process. By exploiting rarely used laws, the government has eroded rights to due process and free speech, affecting both non-citizens and citizens.

Trump has targeted law firms and universities, threatening to withdraw federal funds and contracts unless they align with his agenda. These actions are viewed as violations of the First Amendment and are part of a larger campaign against institutions critical of the administration.

The administration's financial maneuvers, such as freezing foreign aid and imposing tariffs under questionable legal authority, challenge Congress's control over government spending. These actions could undermine the separation of powers and destabilize international economic relations.

Independent agencies have faced interference with the removal of their leaders, raising concerns about the balance of power between the executive branch and Congress. Scholars anticipate potential Supreme Court support for Trump's actions, which aligns with conservative views on executive power.

Despite criticism, some of Trump's actions, like certain appointments and pardons, fall within presidential prerogatives, yet their execution raises alarms about unchecked power. The breadth and speed of these policies obscure legitimate exercises of authority.

The judiciary remains a critical check on Trump's administration, with over 200 legal challenges filed. However, concerns persist about the administration's compliance with court orders and potential congressional actions to limit judicial power, posing risks to the rule of law.
