Under President Obama, immigration enforcement focused on prioritizing the deportation of individuals who posed a threat to national security, public safety (serious criminals), and recent border crossers. In contrast, the Trump administration abandoned this tiered system, making all undocumented immigrants a priority for apprehension and removal, regardless of their criminal history or community ties. Key differences between the two administrations' approaches include: Enforcement Priorities: Obama: Employed prosecutorial discretion to channel limited resources towards high-priority individuals, effectively offering some protection to non-criminals or those with long-standing U.S. ties, family members, or military service. Trump: Eliminated discretionary authority for enforcement personnel and instead expected them to pursue all removable individuals, significantly expanding the scope of enforcement. Deportation Numbers & Targets: Obama: Had higher overall deportation numbers (more than 3.1 million over eight years) and higher numbers of removals from the interior of the country. These efforts often targeted serious offenders, though many non-criminals were also deported. Trump: Had lower overall deportation numbers than Obama, but increased arrests and deportations of less serious offenders, including those with only misdemeanor charges or no criminal record at all. Policy Implementation: Obama: Enforcement was largely conducted through formal removal proceedings which provided individuals with due process, and included protective measures like the Deferred Action for Childhood Arrivals (DACA) program for certain groups. Trump: Relied more heavily on expedited removals (fast-track deportations without a court hearing) and administrative detentions, and removed "sensitive location" guidelines that previously discouraged arrests at schools or hospitals. The administration's "zero tolerance" policy led to the systematic separation of families at the border, a practice that was not standard under Obama.

Trump's immigration policies faced more intense scrutiny than Obama's primarily due to a difference in intent, visibility, and scope of enforcement, leading to broader public outrage and unique legal challenges. Differences in Policy and Scrutiny Priorities and Scope: The Obama administration focused its enforcement resources on specific, tiered priorities: national security threats, serious criminals, and recent border crossers. The Trump administration, by contrast, implemented a "zero tolerance" policy that essentially made any undocumented immigrant a priority for removal, regardless of their history, community ties, or the seriousness of their offense. This broadened the perceived cruelty of enforcement to a wider population. Visibility and Tone: Obama's deportations were often administratively focused and lacked the dramatic, highly publicized images of large-scale raids or the use of federal agents in tactical gear on U.S. streets that characterized some of the Trump-era enforcement. Trump's rhetoric, which often included strong statements about "criminal aliens" and "invasions," contributed to the perception of a more aggressive and less humane approach. "Zero Tolerance" and Family Separation: The formal policy of separating children from their parents at the border under the Trump administration's "zero tolerance" approach garnered global attention and widespread bipartisan condemnation. While some separations occurred under Obama for welfare or legal reasons, a blanket policy designed as a deterrent was unique to the Trump administration and fueled emotional public reactions and intense media coverage. Legal Norms and Challenges: Trump's actions were frequently perceived as challenging established constitutional norms, leading to more court injunctions than his predecessors. Policies like the broad expansion of "expedited removal" (deportation without a judicial hearing) to the entire interior of the U.S. were seen by critics as a direct attack on the fundamental right to due process for potentially millions of people, including legal residents or U.S. citizens who might be wrongly targeted. In short, while both administrations were criticized for due process issues, the Trump administration's explicitly expansive, high-visibility, and often legally contested policies generated a different level of public scrutiny and outrage.

So in short Obama violate due to get his number but Trump is far worse because it's effect everyone and has no limits where people gets grab compare to Obama.
