In a speech at the UN, Trump called the International Criminal Court a "rogue institution." Across his administration, he's used emergency powers to sanction ICC judges and staff. @brennancenter.org just filed a brief explaining why *Trump's sanctions* are rogue and illegal. /1

For those surprised by this, worth noting that the only years since 1997 when the US *hasn't* bombed targets in Iraq were 2012, 2013, and 2022 (and there are some indications there may have been unannounced strikes in 2022). At least monthly strikes through July 2021; strikes on at least...

New from me on the Monroe Doctrine and constitutional war powers. Many thanks to @lawfaremedia.org for letting me walk readers through a century of war powers practice under the doctrine--practice that reveals + reinforces real constraints on presidential power. www.lawfaremedia.org/article/the-...

The Monroe Doctrine Was Never a Blank Check for Presidential War
Trump’s “Donroe Doctrine” in Latin America inverts a policy that, properly understood, abided by and reinforced constraints on unilateral presidential force.

Noteworthy that this identifies War Powers Resolution "hostilities" reports submitted on June 12 and June 29. The White House did not publish these reports, but they constitute formal acknowledgement that War Powers Resolution hostilities continued throughout the so-called "ceasefire" period.

In case you’re wondering, JSOC’s current generals/admirals who reportedly were pushing this are: commander Lt. Gen. Jon Braga (Delta alum), deputy commander Brig. Gen. Terence Taylor (AFSOC MC-130 guy), and assistant commander Rear Adm. Bart Randall (SEAL, but without a ton of Team 6 time).

On war powers, executive-branch lawyers simply ignore when Congress pushes back and write their memoranda as if the pushback never happened. The problem here is that the Court has absented itself from war powers conversations, refusing to check increasingly dubious "legal" interpretations.

Notable too that Thomas cites the Alien Enemies Act -- a law used for internment during WWII -- as a positive immigration precedent. Setting aside the horrors of internment, the Alien Enemies Act is not an exercise of Congress's plenary power over immigration as opposed to *the literal war power.*
