The Trump Administration’s Deregulatory Playbook A deep dive into the Trump administration’s deregulatory agenda, Supreme Court influences, and the evolving limits of agency authority.

"In its first year, the second Trump administration moved quickly and aggressively to rescind many environmental, health, and consumer regulations," write our Katherine Welty and Max Sarinsky in @justsecurity.org.

But there are exceptions, they add.

We discuss potential solutions in a @trellisgroup.bsky.social article.
