Trump's executive orders on immigration were among the most significant, as he sought to restore policies from his first term. This included reinstating the 'Remain in Mexico' policy, which requires asylum seekers to wait in Mexico while their claims are processed, and declaring a national emergency at the U.S.-Mexico border. Trump also designated drug cartels as foreign terrorist organizations, a move that could potentially involve U.S. military action. Furthermore, he signed an order aiming to end birthright citizenship, a right enshrined in the 14th Amendment, though this is expected to face legal challenges [1].

In a controversial move, Trump pardoned over 1,500 individuals charged in connection with the January 6 Capitol riot. This included members of extremist groups like the Oath Keepers and Proud Boys, who were convicted of serious offenses. The pardons have been criticized as undermining the Justice Department's efforts to hold those responsible accountable. Trump defended these actions as correcting what he described as a 'grave national injustice' and claimed they were part of a broader effort to promote national reconciliation [2].

Trump also signed orders to withdraw the U.S. from the Paris Climate Agreement and the World Health Organization, echoing actions from his first term. These moves have raised concerns among scientists and international leaders, who fear they could reverse progress in combating climate change and managing global health crises. Trump's decision to withdraw from the Paris Agreement is particularly contentious, as it distances the U.S. from global climate initiatives and could influence other countries to reconsider their commitments [3].
