In November 2014, President Obama announced an expansion of the Deferred Action for Childhood Arrivals (DACA) program through an executive order. The policy would protect over 700,000 more children of undocumented immigrants from deportation. Republican members of Congress denounced the order as an abuse of executive power. Previously, members of the House of Representatives had voted to defund the program. This scenario best illustrates which of the following? (A) A reluctant bureaucracy can hinder a president's agenda. (B) Public opinion can influence how Congress responds to a president. (C) Iron triangles form between members of the president's party and opponents in Congress. (D) Presidents exert informal powers when their policy agenda conflicts with that of Congress.

In the context of DACA's expansion, we see a clear clash between the executive branch and Congress, showcasing how presidents often take matters into their own hands when faced with resistance from legislative support. This scenario illustrates how informal powers, such as executive orders, come into play when a president's policy agenda is at odds with Congressional action or inaction. Furthermore, this event also highlights the tension within American politics, as differing interpretations of executive power lead to intense debates about the limits and authority of the presidency. This situation illustrates how unresolved controversies can become pivotal in shaping future immigration policies and the overall legal landscape for undocumented individuals in the United States.
