CHICAGO (AP) — President Donald Trump’s attempts to deploy the military in Democratic-led cities—over the objections of mayors and governors—have brought a head-spinning array of court challenges and overlapping rulings.


As the U.S. Supreme Court ponders whether to clear the way for the National Guard in Chicago, a federal appeals court is hearing arguments in California Gov. Gavin Newsom’s challenge to the deployment of troops in Los Angeles. Guard troops could also soon be on the ground in Portland, Oregon, pending legal developments there.


Here’s what to know about legal efforts to block or deploy the National Guard in various cities.


Judge weighs Guard in Chicago while awaiting Supreme Court ruling


A federal judge in Chicago has already blocked the deployment of Guard troops to the Chicago area for two weeks. On Wednesday, Judge April Perry agreed to extend that order by 30 days, but noted each side could discuss further extensions. Anything she decides may become moot if the Supreme Court issues its ruling.


Attorneys representing the Trump administration stated they might consent to an extension of the block but continue to press the U.S. Supreme Court for an emergency order to allow deployments. They assert, “Every day this improper TRO remains in effect imposes grievous and irreparable harm on the Executive,” according to a Supreme Court filing from Solicitor General D. John Sauer.


Guard deployment in Portland also in limbo


In Oregon, a recent ruling allowed Trump to take command of 200 National Guard troops, yet a separate court order prohibits their actual deployment. U.S. District Judge Karin Immergut issued temporary restraining orders to prevent Trump from calling up the Oregon National Guard for deployment.


Despite a split ruling from the 9th U.S. Circuit Court of Appeals favoring the administration, Immergut's orders remain in effect, complicating potential troop movements.


California legal battle goes before appellate panel


A 9th U.S. Circuit Court of Appeals panel in Pasadena is set to hear arguments regarding the deployment of Guard troops to Los Angeles. A district court previously found the administration violated federal law during early deployments following protests against immigration policies.


Groups aim to stop National Guard deployment in DC


Lawsuits are also emerging in West Virginia, where groups are seeking to bar deployment of National Guard members to Washington, D.C., amidst ongoing tensions regarding federal military intervention in civilian governance.


Democrats sue to stop National Guard deployment in Memphis


In Tennessee, Democratic officials have filed a lawsuit against Republican Gov. Bill Lee, claiming his deployment of the Guard breaches state constitutional requirements—underscoring the polarized legal landscape surrounding military deployments in domestic affairs.
