D.C. Circuit Hears Merits on Trump's National Guard Takeover of the Capital — Judges Ask Where the Limits Are

NEW (Oct. 14, 2026): More than a year after President Trump deployed National Guard members to patrol the streets of the nation's capital, the D.C. Circuit heard a 90-minute merits argument in D.C. AG's challenge to the deployment — before a three-judge panel of all Democratic-appointed judges (Pillard, Rogers, Garcia), a notable contrast with the December panel (two Trump, one Obama appointees) that had stayed Judge Jia Cobb's ruling against the deployment.

The argument opened with the panel collectively pressing the government's attorney, Eric McArthur, on whether there are any limits on a president's authority to do this. Judge Cornelia Pillard asked how the government's argument was "not federalization and therefore running up against" the Posse Comitatus Act, the 1878 law forbidding the use of the federal military for domestic law enforcement. McArthur's answer: "I think the limiting principle in our position is the president has to be calling out the guard in aid of the civil authorities." D.C.'s counsel Mitchell Reich was pressed too, holding that the president may deploy the guard "if there's any kind of organized violence in the district."

The stakes and the facts on the ground, per AP:

• Judge Jia Cobb (D.D.C.) concluded last November that Trump's military takeover illegally intrudes on local officials' authority to direct law enforcement in the district — the ruling now getting its appellate test.
• The deployment, extended until January 2029 by the Defense Department, "has taken on a sense of permanence, despite the court case¹": the federal government awarded a $292 million contract to a private company to house Joint Task Force-D.C. members in apartments.
• Troop levels peaked around 5,000 during the semiquincentennial celebration and stood at about 2,900 as of last week.

What it signals: the judicial check on domestic military deployment is now one step from final — an all-Democratic-appointee panel is likely to rule against the government, and AP notes flatly that "even if D.C. wins at the appeals court level, the Trump administration will undoubtedly go to the U.S. Supreme Court, which has already shown deference to the president." Meanwhile the deployment's permanence (a 2029 extension, a nine-figure housing contract) is itself the consolidation story: the executive is building facts on the ground faster than courts can review them.
