President Donald Trump renewed threats on Sept. 5, 2025 to send National Guard or federal law-enforcement personnel into Chicago, Baltimore and New Orleans, even after a federal judge in San Francisco ruled in June that a similar deployment to Los Angeles violated the Posse Comitatus Act; city and state leaders in the three municipalities have publicly resisted the moves and prepared legal and operational responses.
Key takeaways
- A federal judge found the June deployment to Los Angeles violated the Posse Comitatus Act; that ruling currently applies only in California.
- The Department of Homeland Security has asked the Pentagon for logistical support for ICE operations near Chicago, including use of Naval Station Great Lakes facilities.
- Illinois and Maryland governors oppose troop deployments to their states; Louisiana’s governor has welcomed federal help for New Orleans.
- Local officials say violent crime is down in Chicago, Baltimore and New Orleans and have organized legal, operational and community countermeasures.
- Legal experts say the administration could try to invoke the Insurrection Act or federalize Guard units under Title 10, which would likely trigger litigation and possible Supreme Court review.
Verified facts
In June, National Guard personnel were used in Los Angeles in response to protests tied to immigration enforcement; a federal judge in San Francisco later ruled that deployment violated the Posse Comitatus Act, which restricts use of the military for domestic law enforcement. That decision applies in California while appeals proceed.
The Department of Homeland Security has requested Pentagon assistance to support ICE enforcement and removal operations in the Chicago metropolitan area, including logistical help and access to facilities at Naval Station Great Lakes, roughly 30 miles north of Chicago.
Illinois Gov. J.B. Pritzker and Maryland Gov. Wes Moore have publicly rejected plans to send Guard troops into Chicago and Baltimore, respectively. Louisiana Gov. Jeff Landry has endorsed federal assistance for New Orleans, and some federal officials have discussed deploying resources to the city.
Local leaders point to falling violence statistics: Baltimore officials report homicides down 28% year to date and violent crime down about 18% from the same time last year, with just seven homicides in August; New Orleans preliminary police data show roughly a 20% drop in overall crime since last August. City leaders say those trends undercut the administration’s public-safety justification for broad troop deployments.
Context & impact
Federal officials have framed proposed operations as immigration enforcement in some cities and public-safety support in others. Deploying ICE agents to assist with removals differs legally from placing military or Guard personnel in direct policing roles, and that distinction is central to ongoing disputes.
Legal scholars, including Georgetown law professor Stephen Vladeck, note the administration could attempt less-common legal routes: invoking the Insurrection Act, federalizing Guard units under Title 10, or moving personnel from other states. Each option carries legal and political risks and would likely prompt rapid litigation.
On the ground, communities are preparing: Chicago parade organizers have postponed events, neighborhood groups are staging volunteer safety details, and mayors are issuing directives to limit cooperation with federal immigration operations. Officials in New Orleans and Baltimore have warned about diverting National Guard units away from hurricane-season disaster response.
- Potential local impacts: legal fights, increased tensions between residents and federal agents, disruption to community events, and reallocation of Guard resources during hurricane season.
“None of this is about fighting crime or making Chicago safer,”
Gov. J.B. Pritzker
“Well, we’re going in — I didn’t say when, we’re going in,”
President Donald Trump
Unconfirmed
- Whether the administration will deploy National Guard units from other states, such as Texas, into Illinois or Maryland has not been confirmed.
- The specific number of federal agents or troops being planned for any city has not been publicly disclosed.
- Timetables for any operation and whether deployments would follow the Los Angeles model or focus solely on immigration enforcement remain unverified.
Bottom line
Federal threats to send Guard or federal agents into Chicago, Baltimore and New Orleans have prompted swift pushback from local and state officials, even as the White House frames the moves as public-safety or immigration actions. Legal limits such as the Posse Comitatus Act and likely court challenges mean any large-scale, involuntary deployments would face significant hurdles and could end up before the Supreme Court.
