A landmark decision from the U.S. Court of Appeals for the Seventh Circuit has put President Donald Trump’s ‘Operation Midway Blitz’ on hold in Chicago, temporarily blocking the deployment of National Guard troops. This ruling underscores a critical legal battle over presidential authority and the definition of ‘rebellion,’ setting a significant precedent for federal intervention in local affairs.
The ongoing legal saga concerning President Donald Trump’s attempts to deploy federal troops to U.S. cities reached a critical juncture in Chicago this week. A federal appeals court has temporarily barred the Trump administration from sending National Guard troops into the city, upholding a lower court’s decision. This ruling, issued on October 16, 2025, represents a significant judicial check on presidential power, particularly regarding the activation of military forces within domestic borders.
The U.S. Court of Appeals for the Seventh Circuit, based in downtown Chicago, affirmed U.S. District Court Judge April M. Perry’s October 9 decision to block the White House from deploying troops. The administration had argued that protests against its immigration enforcement crackdown, known as Operation Midway Blitz, constituted a rebellion, thereby justifying federal military intervention. However, the appellate judges strongly disagreed.
The Legal Battle: Defining ‘Rebellion’ and Presidential Authority
At the heart of the court’s decision was a fundamental disagreement over the interpretation of federal law regarding presidential authority to activate the National Guard. The court’s ruling stated unequivocally: “The spirited, sustained, and occasionally violent actions of demonstrators in protest of the federal government’s immigration policies and actions, without more, does not give rise to a danger of rebellion against the government’s authority.” This directly challenged the Trump administration’s justification for deployment, which claimed the Guard was necessary to enforce White House efforts to apprehend “the worst of the worst” criminal immigrants, as detailed by USA TODAY.
Illinois Governor J.B. Pritzker had been adamantly opposed to the deployment, calling it “unnecessary” and “a manufactured performance — not a serious effort to protect public safety.” He argued that the administration’s demand for him to deploy his own troops, or face federalization, was “absolutely outrageous and un-American.” Judge Perry herself had expressed concerns that allowing soldiers into the region would “only add fuel to the fire” ignited by immigration agents in and around Chicago.
The National Guard, though part-time federal troops, typically falls under the command of state governors. Federal law permits presidential activation in limited circumstances: foreign invasion, rebellion, or when the president cannot execute U.S. laws with regular forces. Brenner Fissell, a Villanova University law professor, noted that the law requires these conditions to actually exist, not merely be asserted by the president. Courts, while deferring to the president, can review determinations to ensure they fit “within the realm of honest judgment.” This judicial oversight proved critical in Chicago, mirroring earlier decisions in other states.
Operation Midway Blitz: Tactics and Concerns
The proposed deployment to Chicago was part of a broader federal initiative that has seen aggressive tactics in other cities. Under Operation Midway Blitz, Homeland Security officials have defended their actions as necessary for law enforcement. However, these operations have been controversial, marked by incidents such as the fatal shooting of a Mexican immigrant by immigration agents, attempts by federal judges to limit the use of chemical weapons on protesters and journalists, and Border Patrol agents shooting and wounding a woman on Chicago’s South Side. Homeland Security claimed over 1,000 immigrants were arrested in connection with the blitz, though this number remains unverified.
The ACLU of Illinois, through its executive director Colleen K. Connell, strongly condemned the administration’s actions, calling them the “latest escalation of attacks on people in the Chicago area.” The ACLU emphasized that federal agents and troops are generally not trained in local policing or de-escalation, and their deployment risked placing them in “legal and ethical jeopardy.” The organization argued that such moves were an attempt to “create conflict, sow fear in our communities, and intimidate people from exercising their constitutional rights.”
Historical Context of National Guard Deployments
The debate over presidential control of the National Guard is not new, echoing historical precedents that shaped the understanding of federal power versus state sovereignty.
- Origins: The National Guard’s roots trace back to colonial militias in 1636, formed to protect communities. These militias fought under George Washington during the Revolutionary War. The Constitution’s framers, wary of a powerful standing army, kept militias under state control, with Congress defining when the president could call them into service.
- Civil Rights Era: Presidents frequently federalized state National Guard units to enforce federal court orders when Southern governors defied integration mandates. Notable instances include President Dwight D. Eisenhower deploying the 101st Airborne Division to Little Rock, Arkansas, in 1957, and President Lyndon Johnson federalizing the Alabama National Guard in 1965 to protect Selma-to-Montgomery civil rights marchers. The 1965 event marked the last time a U.S. president deployed the Guard against a governor’s wishes before the current situation.
- Civil Unrest: More recently, presidents have federalized the Guard at governors’ invitations to quell unrest. Examples include Michigan’s request for help during the 1967 Detroit riots and California Governor George H.W. Bush’s appeal for assistance during the 1992 Los Angeles riots following the Rodney King verdict.
The Posse Comitatus Act and the Insurrection Act
A key legal constraint on using military forces domestically is the Posse Comitatus Act of 1878, which generally prohibits the use of the military for domestic policing. U.S. District Judge Charles Breyer in California previously found that Trump’s use of the Guard in Los Angeles earlier this year violated this law, a ruling currently on appeal. As Syracuse University law professor William Banks noted, the act establishes a presumption against “soldiers on the street.”
However, there is a major exception: the Insurrection Act. This law allows the president to deploy military forces within the U.S. to suppress rebellion or enforce the law. Presidents Eisenhower, Kennedy, and Johnson invoked it during the Civil Rights Movement, and President Bush during the LA riots. President Trump has repeatedly suggested he is open to invoking it if courts continue to block his deployments, a move that Banks warned would effectively remove “all brakes” on the administration’s ability to militarize a city, as noted by Yahoo News.
Implications for Federalism and Civil Liberties
The Chicago ruling, following similar temporary blocks in Oregon and a legal challenge in California, highlights a profound tension between federal and state authority. While the Trump administration argues for its right to protect federal property and enforce immigration laws, states and cities contend they are fully capable of maintaining order and that federal military interference is unwarranted and potentially dangerous. The courts are carefully navigating the balance between executive power and constitutional limits, especially concerning civil liberties and the proper role of the military in domestic affairs.
This ongoing legal battle is more than just a dispute over troop deployment; it is a defining moment for federalism, civil liberties, and the interpretation of presidential authority in times of domestic unrest. The outcome of these cases will undoubtedly shape the future relationship between federal military power and local governance, setting precedents for how the U.S. addresses internal conflicts for years to come.
