The Deeper Problem with ICE's Arrest Warrants DHS regulations do not ensure that ICE warrants are supported by probable cause findings. This poses significant Fourth Amendment risks.

Congress is fighting over whether ICE needs a warrant to enter your home. But ICE arrest warrants aren’t reliable enough to protect anyone from wrongful detention, writes Chris Hardee (@stereotopical.bsky.social).

Why — and how Congress must fix it:

For Lasting Stability, Venezuela Needs a Peace Process Venezuela needs a peace process built on rigorous national dialogue and power-sharing to heal internal fractures and rebuild institutions.

In the transition since the U.S. capture of President Maduro, #Venezuela has a potential path to return to democratic governance and a more productive long-term relationship with the United States.

Double Preemption, Imminence, and the U.S. Attack Against Iran Rubio’s argument that Operation Epic Fury was preemptive self-defense is not credible and does not satisfy the necessary precondition.

Secretary Rubio's "double-preemption argument fails, simply because you cannot double-preempt against an action to which you are yourself a party."

How a Broadly Defined Counterterrorism Statute Could Be Abused 18 U.S.C. § 2339A doesn’t require proof of membership or terrorist intent, and the policy framework around it outweighs any single verdict.

A Texas trial is the first major test of the Trump administration’s push to prosecute alleged “antifa” adherents as domestic terrorists. But Thomas Brzozowski argues that the criminal statute central to the government’s case is overly broad – and could easily be abused.
