‘One Voice’ and the Trump Administration’s Conduct of Foreign Affairs
A new executive order deploys a contested theory of presidential authority—and uses it to target the public servants responsible for conducting America’s foreign relations.

Calls are getting louder to allow the transfer of Russian frozen assets to support Ukraine as the U.S. pulls back. About 250B (of roughly 300) are held in EU. When this proposal was debated before many—Biden officials included—concluded that such transfer would likely be unlawful.

For ad law folks - among the dozens of EOs issued there’s also one formalizing the structure of what has so far been known as DOGE. It’s going to be an office within the EEOP, not a full fledged agency, with broad access to agency infrastructure. One implication: administrator needn’t be confirmed.
